Ingredient Notes and Substitutions
- Flax seed: I prefer to grind my own flax because the ground flax in the store is so often rancid. If you don't have a machine that can grind it, buy it pre-ground.
How to Make a Flax Egg
Step 1: grind the flax seed into a fine powder in a dry ingredient safe blender, small food processor, or coffee grinder.
Step 2: mix the water and ground flax together and set aside for a few minutes to gel.
Top Tips
- Do a sniff test: if your flax has gone rancid, you'll be able to smell it. Flax seed has a slightly oily scent (some find that it smells a little fishy) and that's normal, but if it's rancid, it'll smell unpleasant.
- Let it rest: the flax egg needs a few minutes to thicken and allow the flax to absorb the water.
- Stir very well: you don't want any dry bits in the egg, so be sure to mix the water in really well.
How to Store
Store whole flax seeds and ground flax meal in the fridge or freezer as they have a high risk of going rancid at room temperature. Ground flax will last in the fridge for up to 3 months, and in the freezer for up to a year. Whole seeds can be kept in the fridge for up to 6 months.
When to Use Flax Eggs
While it's best to start off with a vegan recipe in the first place, if you want to try subbing it in an egg recipe, you can start here:
- Flax eggs are a good option in recipes where another rising agent, like baking soda or baking powder, is used.
- Dishes that are already fibre-forward, like baked oatmeal and whole grain muffins work well.
- They work well in most quick breads and muffins, and can be used in some cookies, like these vegan gingerbread cookies or vegan carrot cookies.
When Not to Use Flax Eggs
- Flax eggs aren’t great in recipes where eggs play a pivotal role, like meringues or egg custards.
- Don’t use a flax egg when you don’t want the fibre to be visible. Because flax eggs add tiny specs of flax to your dish, be sure this isn’t a problem (like for a white cake).
- They also aren’t useful where eggs provide most of the leavening (in a Dutch baby or angel food cake, for example).
