Aquafaba is the water you obtain from cooking chickpeas (or other legumes). The aquafaba I use is water drained from a chickpea can. I prefer low or no sodium chickpea water, mainly because of the taste, I feel like the salted chickpea water adds a weird taste to meringues and such. Some people like to boil their own chickpeas to obtain the aquafaba, and you can do that, but make sure to study what are the best ratios water:chickpeas so your aquafaba is concentrated enough
Aquafaba: I used to reduce the aquafaba before. But lately, I haven’t been reducing it anymore, and it works just fine. If you do want to reduce the aquafaba, place 150 grams of aquafaba in a small saucepan and bring to a boil, simmer until it reduces to about half. I recommend using the aquafaba straight from the chickpea can.
Macaronage: If you are acquainted with making regular (egg white) macarons, one of the clues about knowing when the batter is ready to be piped, is when you can grab some batter with the spatula and start drawing a figure 8, if the batter doesn’t break up as you draw a few figure 8 shapes, that means the batter should be ready. However, I am learning with vegan macarons that it’s optimal to stop folding the batter right before it reaches this stage. Please watch my videos on youtube, as you can see in the videos what the batter should look like.
Thick batter: If the batter is too thick while mixing, add a teaspoon of aquafaba as you mix, until you obtain the perfect consistency.
Oven thermometer: Please make sure to have an oven thermometer! I receive a lot of troubleshooting questions and the great majority are issues caused due to not having an oven thermometer. Read this post for more detailed information about how important this is.
Oven temperature: Please experiment with your own oven temperature. Temperatures will vary depending on your oven and technique. It’s important to experiment and see what works best for your own oven. In my old oven I used to bake this same recipe at 310ºF. However, with my new oven, I bake it at 285ºF. This comes to show that the temperature will vary greatly depending on your own oven. Please experiment and find out what works best for you.
