People with experience baking crackers
I was wondering if you had any ideas about ingredients or techniques that make crackers extra crispy and crunchy.
I like crackers super crunchy so I bake them at 350F with the convection fan on until they are nicely browned. This is always longer than the recipe states. Convection mode also helps remove the water from the crackers.
50ish%, and a good formula will guarantee good results.
Using ammonium bicarbonate ("bakers' ammonia") instead of baking soda can help - if it's even sold anymore.
It's no good in a cake, but for crackers and thin crispy cookies it apparently makes a positive difference.
It’s available on Amazon. German bakers use this quite a bit to give their cookies extra crunch.
What % should we use in the dough? Thx.
Same percentage as baking powder. It’s a one-to-one substitution.
Do you treat it the same way as baking soda (which needs some source of acid in the recipe, either added or inherent in the main ingredients) - or does it work alone, like baking powder does? [If you make a naturally-alkaline recipe and you add baking soda without acid, you get no leavening action, and your finished product tastes like baking soda.]
I've never used bakers' ammonia, just knew it existed and was good for this purpose.
I think "follow the recipe you already have" is a safe assumption. There isn't one absolute answer that's perfect for all cases. No need to reinvent the wheel.
the recipe doesn't call for baking powder? Can I just add some to make my crackers more crunchy? Then I'll need to know what % to use.
I wouldn't use any leavening agent in a recipe that didn't even call for one. If your current cracker recipe has no baking soda, no baking powder, and no other leavening agent, I say carry on making it the same way. Try a new recipe if you like - there are lots of them. There are so many good cracker recipes out there - trying to modify your current recipe to be a whole different kind than it was intended to be, is likely a waste of time. The problem is already solved, many times over - no need to work hard solving it over again.
It's a lot like "How do I modify my house to turn it into a lumber mill?" - technically you could do it, but it would be easier and cheaper to build a lumber mill next door and leave your house as it is.
