Clay extruders and fondant have a difficult relationship, and almost everyone diagnoses it wrongly. The extruder jams, the fondant tears, a rope comes out uneven — and the conclusion is that a better extruder is needed. Usually it is not.
Polymer clay and fondant behave completely differently in a barrel. Polymer clay is firm, slightly greasy and dimensionally stable at room temperature. Fondant is sugar and glycerine: it is sticky, it softens as it warms, and warm hands plus a warm barrel plus the pressure of extrusion make it softer still as it goes. So a rope that starts clean turns sticky and tears halfway through, and the fondant grips the inside of the barrel instead of sliding down it. That is chemistry, not a design flaw in the tool.
Which means the fixes are technique, and they work on almost any extruder:
Chill the fondant. Twenty minutes in the fridge before loading makes it noticeably firmer and dramatically easier to extrude cleanly. Work in small quantities so the rest stays cold.
Grease or dust the barrel. A very light coat of vegetable shortening inside the barrel and on the disc, or a dusting of cornflour, breaks the grip. Shortening generally works better on fondant; cornflour can dry the surface.
Add a little gum tragacanth or CMC to the fondant. It firms the paste and helps it hold a shape once extruded, which is what turns a sagging rope into a usable one.
There is one thing a better tool genuinely fixes. Squeeze-handle extruders cannot produce steady pressure, and fondant needs constant even force or the rope comes out in pulses of varying thickness. A screw-plunger extruder, where you turn a handle and the plunger advances slowly and evenly, solves that completely and is the single upgrade worth paying for.
And one non-negotiable: an extruder sold for clay is not food-safe. Keep one dedicated to food and never cross-use it.

The picks, in detail
Screw-Plunger (Turn-Handle) Extruder
The upgrade that genuinely helps. Turning a threaded handle advances the plunger slowly and with constant force, which is exactly what fondant needs — a squeeze handle delivers pressure in pulses and produces a rope of varying thickness. It also requires far less hand strength, which matters when you are producing several metres of rope for a basketweave. Look for a metal barrel, a threaded plunger that runs smoothly, and a disc set that seats properly without gaps.
- Threaded plunger advanced by a turning handle
- Constant, even extrusion pressure
- Metal barrel and plunger
- Set of interchangeable discs
- Even pressure gives a consistent rope thickness
- Requires very little hand strength
- Handles firmer pastes a squeeze handle cannot
- Slower than a squeeze extruder
- Cheap threads bind and feel gritty
Squeeze-Handle Extruder
The common format, and it works with the right technique even if it is not ideal. A lever squeezed by hand drives the plunger, which is fast and intuitive and delivers pressure in pulses rather than evenly — so ropes come out with slight thickness variation. With chilled fondant, a greased barrel and short runs it is perfectly usable, and it is much cheaper than a screw extruder. A reasonable first purchase if you are finding out whether you will use one at all.
- Lever-operated plunger
- Fast extrusion
- Metal or plastic barrel
- Disc set included
- Fast, and intuitive to use
- Much cheaper than a screw extruder
- Fine for short runs with chilled paste
- Pulsed pressure gives uneven thickness
- Needs real hand strength with firm paste
Food-Safe Sugarcraft Extruder
The one to buy if you are working with food, and the distinction matters. Extruders sold for polymer clay use materials and lubricants that were never assessed for food contact, and clay residue in the barrel threads is not something to serve. A sugarcraft-branded extruder is made from food-grade materials and usually comes with discs shaped for the things fondant work actually needs — ropes, ribbons, hair strands, basketweave. Keep it exclusively for food, always.
- Food-grade materials throughout
- Discs shaped for sugarcraft applications
- Dishwasher safe on many models
- Sold through cake decorating suppliers
- Materials assessed for food contact
- Disc shapes suited to fondant work
- No cross-contamination worry
- Fewer disc shapes than clay-oriented sets
- Slightly more expensive for the same mechanism
Additional Disc Sets
Where the versatility actually comes from. The barrel is the same; the discs are what produce a round rope, a flat ribbon, a square, a triangle, a multi-strand hair texture or a rope shape for basketweave. Extra disc sets are cheap and transform what one tool can do. The two things to check are that they fit your specific barrel diameter — sets are not universal — and that the holes are cleanly cut, since a burr on the edge drags fondant and tears the rope.
- Round, square, flat and multi-hole patterns
- Sized to specific barrel diameters
- Stainless steel on better sets
- Sold in sets of 16 to 20
- Cheap way to multiply what the tool can do
- Multi-hole discs make hair and grass instantly
- Stainless sets do not rust
- Not universal — check your barrel diameter
- Burred holes drag and tear the paste
Gum Tragacanth or CMC Powder
The additive that changes how fondant behaves in an extruder, and the one most people do not know about. A small amount of gum tragacanth or CMC kneaded into fondant firms it up and makes it hold a shape once extruded rather than sagging — which turns a rope that slumps into one you can lay into a basketweave. It also speeds drying, so the piece sets rather than staying soft. Add a little, knead thoroughly and let it rest before extruding; it needs time to hydrate.
- Gum tragacanth or CMC (tylose) powder
- Firms fondant and speeds drying
- Very small quantities needed
- Long shelf life
- Makes extruded shapes hold their form
- Turns fondant into modelling paste
- A small tub lasts a very long time
- Needs resting time to hydrate properly
- Too much makes the paste crack and tear
Vegetable Shortening
The unglamorous fix that solves most extruder problems. A very thin coat inside the barrel and on the disc stops fondant gripping the metal, which is the actual cause of most jamming, tearing and uneven extrusion. A trace on your hands and the work surface does the same. The key word is thin — too much and the extruded rope is greasy and will not take colour or stick to anything. Wipe the barrel with a shortening-touched cloth rather than applying it directly.
- Plain white vegetable shortening
- Applied as a very thin film
- Also used on hands and work surfaces
- Long shelf life
- Solves the gripping that causes most jams
- Costs almost nothing
- Also stops fondant sticking to hands and boards
- Too much leaves a greasy surface that will not stick
- Needs reapplying between barrels
Fondant Smoother and Rolling Pin Set
Supporting tools for everything an extruder does not do. A non-stick rolling pin with guide rings gives you fondant at a consistent thickness, which matters because an extruder needs paste of roughly even firmness and a sheet rolled unevenly has dried out in patches. A smoother flattens and finishes covered surfaces so extruded detail has something clean to sit on. Both are basic and both are what separates a tidy finish from an obviously handmade one.
- Non-stick rolling pin with thickness guide rings
- Rigid smoother with a handle
- Food-safe plastics
- Wipe-clean surfaces
- Guide rings give consistent thickness
- Smoother gives extruded detail a clean base
- Cheap and immediately useful
- Guide rings only fit their own pin
- Smoothers scratch and then mark the fondant
Silicone Work Mat with Measurements
The surface that makes extruded work accurate. A printed mat with circles and measurements lets you cut ropes to exact lengths and roll sheets to a known diameter, which is what turns a decorated cake from approximately right into actually right. Silicone releases fondant far better than a worktop, so a light dusting is enough rather than a thick one — and less dusting means less drying out. It rolls up and it goes in the dishwasher.
- Printed circles and measurement guides
- Non-stick silicone surface
- Rolls for storage
- Dishwasher safe
- Measurements make extruded lengths repeatable
- Releases fondant with minimal dusting
- Protects and keeps the worktop clean
- Thin mats slide on a smooth counter
- Printed guides wear off with heavy use
Airtight Storage Containers and Cling Film
Fondant’s real enemy is air, and a paste that has crusted is one that will jam an extruder and tear as it comes out. Any fondant not currently in your hands should be wrapped tightly in cling film and inside a sealed container — that is two layers, and both matter. It also lets you chill working quantities in the fridge, which per the introduction is the single most effective technique fix. Small containers are better than one large one, since each opening exposes the contents.
- Airtight containers in several sizes
- Cling film for direct wrapping
- Stackable and fridge-friendly
- Clear so you can see the colour
- Stops the crusting that causes tearing
- Lets you chill working quantities easily
- Small containers limit air exposure
- Needs genuine discipline to use every time
- Coloured fondant stains plastic
Extruder Cleaning Brushes and Pin Set
Because a disc with dried fondant in its holes tears every rope that follows, and the holes are too small for anything you already own. A set of fine brushes and pins clears them properly. Clean immediately after use — dried sugar paste in a small hole is genuinely difficult to remove and soaking a metal extruder risks rust in the threads. A quick brush-through while everything is still soft takes a minute and keeps the tool producing clean ropes.
- Fine brushes and clearing pins
- Sized for small disc holes
- Handles for grip
- Compact set
- Clears disc holes nothing else reaches
- Prevents the tearing a partly blocked disc causes
- Cheap
- Must be used immediately, before residue dries
- Soaking a metal extruder risks rust in the threads
Buying tips
- Chill the fondant before you extrude it. Twenty minutes in the fridge makes it noticeably firmer and dramatically easier to push through cleanly. Warm hands, a warm barrel and extrusion pressure all soften it further as you work, which is why a rope that starts fine turns sticky halfway through. Work in small quantities so the rest stays cold.
- Grease the barrel and the disc. A very thin film of vegetable shortening breaks the grip that causes most jamming and tearing. Apply it with a cloth rather than directly, because too much leaves a greasy rope that will not take colour or stick to anything. This one habit solves more extruder problems than any upgrade.
- Add gum tragacanth or CMC. A small amount kneaded in firms the paste and makes extruded shapes hold their form instead of sagging, which is what turns a slumping rope into usable basketweave. Knead it thoroughly and let the paste rest so the gum hydrates before you extrude — added and used immediately it does very little.
- A screw-plunger extruder is the upgrade worth paying for. Squeeze handles deliver pressure in pulses, and fondant turns that into a rope of varying thickness. A turn-handle extruder advances the plunger slowly and evenly, producing a consistent rope with far less hand effort. It is the one thing a better tool genuinely fixes.
- Never use a clay extruder for food. Materials and lubricants in tools made for polymer clay were not assessed for food contact, and clay residue in barrel threads is not something to serve. Buy a food-safe sugarcraft extruder and keep it exclusively for food, with no exceptions in either direction.
- Keep everything you are not using wrapped and sealed. Fondant crusts on contact with air, and crusted paste jams and tears. Cling film directly against the surface, then inside an airtight container — two layers, both needed. Several small containers beat one large one, because every opening exposes what is inside.
- Clean the discs immediately. Dried sugar paste in a small hole is very difficult to remove and a partly blocked disc tears every rope after it. Brush them through while everything is still soft. Avoid soaking a metal extruder, which puts water into the threads and the barrel where it causes rust.
- Warm the barrel in your hands if the paste is too stiff. The opposite problem to the usual one, and it happens with heavily gummed paste or on a cold day. A minute of holding the loaded barrel softens the fondant just enough to flow. Do not use hot water — that softens it past the point where it holds a shape.
