Ever tried a keto waffle that was *totally* crisp without a gimmick? Introducing my gluten free and keto sourdough waffles! Perfect for a fabulous breakfast or even as an easy bread hack... with actual yeast!
Add yeast and inulin (or maple syrup) to feed the yeast to a large bowl. Heat up heavy whipping cream with water to 105-110°F, and if you don't have a thermometer it should only feel lightly warm to touch. Pour water over yeast mixture, cover bowl with a kitchen towel and allow to rest for 7 minutes. The mixture should be bubbly, if it isn't start again (too cold water won't activate the yeast and too hot will kill it).
Mix your flours while the yeast is proofing. Whisk thoroughly together lupin flour, golden flaxseed meal, almond flour, baking powder, xanthan gum and salt in a small bowl. Set aside.
Once your yeast is proofed, whisk in the eggs, room temp melted butter (you don't want to scramble the eggs or kill the yeast!) and vinegar. Add the flour mixture in two batchesr. Your batter will be thick, but 'elastic'.
Cover with a kitchen towel and place in a warm draft-free space for 1 hour. I like to turn on my oven until *just* warm (think a summer day at the beach!), and let it hang in there. Note that after it has doubled in size, you can cover it and pop it in the fridge overnight.
Heat up your waffle iron (if available use a lower heat setting, as keto batters prefer a slower 'cook'). Butter it super duper well and spoon a couple tablespoons or so of the batter. It will be thick, so spread it out a bit using a wet spatula (or wet the back of a spoon). Close waffle iron and cook for 7-11 minutes until fully golden and cooked through. I've found that cook time varies a lot here (takes longer in a Belgian-style iron, for e.g.), so I def suggest doing a test run here.
Serve right away! Though I've found that these can be stored for a couple days in an airtight container, and crisp up quite well once again. But nothing quite beats a fresh waffle, iykwim. :)
Notes
*I've found that the texture of these waffles comes out best when using a mixture of heavy whipping cream and water. But you can also do all half and half, or sub with half milk of choice (almond, etc) + 1 egg (and skip the water!).Please note that this recipe yields 2 large Belgian-style waffles (i.e. 8 triangles or American-style square waffles), and the nutrition facts where calculated per piece.
