Gluten-free baking troubleshooting

Six practical questions

Understand the bake before changing the recipe.

Why is the centre of my gluten-free bake gummy?

First check the recipe, measured ingredients, oven temperature and cooling time. Too much liquid or binder, an underbaked centre or slicing while hot can all give a gummy result. A flour blend designed for a different type of bake can also change how moisture is absorbed and the structure sets.

Let the bake cool as directed before judging the crumb, and record one change at a time on the next attempt. Do not keep adding gum because the loaf lacks structure. Use the recipe’s doneness checks; a browned surface alone does not tell you whether a deep loaf has baked through.

Why does a cake sink after it comes out of the oven?

A cake needs enough set structure to hold the rise. Incorrect measuring, too much raising agent, an underbaked centre or opening the oven early can all contribute to collapse. A major flour or liquid substitution can change the balance even when the cake looked promising during baking.

Check the tin size and oven setting against the recipe, weigh the ingredients and resist increasing the raising agent as a quick fix. Cool the cake as directed. If it repeatedly sinks, keep a record of the blend and method so you can investigate one cause instead of changing four ingredients at once.

How do I stop pastry cracking when I roll it?

Follow the recipe’s hydration and resting directions, then work with a manageable piece while the rest stays covered. Gluten-free pastry does not stretch like wheat pastry, and a dry surface can crack before the centre has hydrated. Rolling between suitable sheets of baking paper can reduce handling and extra bench flour.

Check whether the recipe calls for chilled or slightly softened dough rather than warming it at random. Patch small tears gently and avoid rolling so thinly that the pastry cannot be lifted. If it crumbles everywhere, revisit the measured liquid and binder before blaming the rolling pin.

Should I replace every flour by the same weight?

Weight is more consistent than cups, but equal weight does not make different flours functionally identical. Rice flour, starches, nut meals and wholegrain flours absorb and set differently. A recipe may rely on a blend’s binder or protein content, so a straight swap can change spread, rise or crumb.

Start with a tested formula for the bake you want. Check blend ingredients before adding more xanthan or psyllium, and trial a small batch if you must substitute. The Kitchen Skills flour guides explain those roles without prescribing a universal flour mixture for bread, pastry and cakes.

How can I improve a dry or crumbly bake?

Check overbaking, flour measurement, cooling and storage before pouring more liquid into the next batch. Scooping flour tightly into a cup can add more than intended; changing the blend may also increase absorption. Some gluten-free bakes need a specified rest so the flour hydrates before baking.

Weigh ingredients, follow the stated fat and binder quantities and keep the tin size consistent. Once cool, store the bake appropriately or freeze suitable portions before it dries out. A sauce or topping can make a dry slice nicer to eat, but it does not identify what caused the texture problem.

How do I tell whether my oven is the problem?

Use a suitable oven thermometer and give the oven and baking surface time to preheat. Check whether the recipe specifies fan-forced or conventional heat, and use the recommended shelf position. Hot spots, a crowded oven or a different tin can alter browning and the time needed for the centre.

Record the setting and result before changing the recipe. Rotate only when the bake can tolerate opening the door, and follow its doneness checks instead of relying on the timer alone. An oven thermometer helps assess air temperature; it does not replace a food probe where a safe core temperature matters.
