How long will the Waffle Batter keep in the fridge for?
Waffle batter is similar to pancake batter and is based on eggs, flour and milk. It is possible to keep the batter in the fridge and the eggs are the most perishable ingredient so they tend to set the keeping time. We would prefer to keep the batter for up to 2 days after making it and it should be kept refrigerated at all times. The batter should be transferred to an airtight container or left in a tightly covered jug. You may find the batter separates a little as it stands but it can be whisked gently to bring it back together.
You may also find it easier to cook a full batch of waffles and then store the cooked waffles in the fridge (wrapped in clingfilm/plastic wrap or in an airtight container) for up to 3 days. The waffles can be reheated in a toaster or under a preheated grill (broiler).
