I don’t know how to make or cook anything, so I need help with deciding how much milk I am supposed to put in a peanut butter shake, how much PB, bananas,etc. , but in metric units, since I’m from Europe. For example let’s say I want base my shake on **50 grams** of peanut butter, how much milliliters of milk would I need? Would like 200ml be good enough or would it be too dense? Would a single medium sized banana be good or maybe too little/too much? I am looking for exact figures, not cups, tea spoons,etc, since I want to calculate the nutrients as closely as possible. ---

The recipes I’ve seen call for 1 unit peanut butter, 4 units of milk, 4 units of ice cream. 1 ml of milk is 1.035 grams, so 200 ml would be a little dense, but probably close enough. A peanut butter shake only contains peanut butter, milk, and ice cream. Adding a banana makes it a banana peanut butter shake, which is a tasty treat but not the same thing. ---

A cup can be a an exact figure, the US liquid measurement unit is 237 ml. A teaspoon is likewise an exact measure. If you use a measuring spoon rather than any old spoon, it will be 3 ml. And what you’re asking about is a matter of taste. Find an approximate recipe to what you are after and experiment. ---

I make PB and banana shakes. I start with about one cup of (unsweetened) almond milk, and add half a banana and two heaping tablespoons of PB. Then I blend it. If it looks too thick to drink, I add more milk. If it looks too thin, I add more PB. My recommendation: experiment, keep good notes, and settle on what works for you.
