The other day, my husband did an attempt to make buttermilk for my mother in law. The thing is, it just didn't settle. It was probably the chilly living room temperature (despite the jug with milk being covered in a thick blanket). Or he didn't use the right amount of yogurt. Whatever it was, we were left with one litre of milk- not tasting good enough to drink as is, nor suitable to use as buttermilk. So I figured it would be best to use for baking. Most baking recipes are very forging when it comes to the milk you're using- I've used spoiled milk, plant "milk" (such as rice/oats), very watered down milk, watered down yogurt or even whey. So I knew it was possible to use this failed buttermilk for baking.
Baking pancakes was a no brainer, but I already made quite a large batch of pancakes that I froze to have a quick breakfast. And we had waffles two days ago. So I thought it would be better to make something different. Muffins it was- the children are always happy to have a nice after school snack anyway. I usually use white flour when baking muffins but I was in for something more adventurous today and decided to use a mix of white flour, whole wheat flour and oat flour. I used half of the milk but there was some batter left over, since I didn't have enough muffin molds. So I added more milk and flour mixture to bake another batch of "muffins", in a cake pan. Sometimes you just need to be creative, right?
And then, there was *still* some batter left- I was afraid the cake would rise too high and I'd end up with a messy oven if I'd add all of the batter into the cake pan. So, I used my trick to turn muffin batter into pancake batter, by adding around 1/2 cup of flour and as much liquid as needed. This is because muffin batter contains slightly more baking powder than pancake batter. And there I was left with some more pancakes anyway! Which is OK, I'll just have some pancakes for lunch today, and possibly some more for tomorrow's breakfast, and the rest can be frozen.
See, this is how many low waste/frugal people live their lives: they're led by whatever needs to be rescued, rather than sticking to a certain plan. I'm sure it's more convenient to just toss that nearly-spoiled milk out and follow whatever meal plan you already made, but for me it's become such a habit, it doesn't even feel like a hassle.
