I'd like to start by saying that this indeed is a neat site!
Now for my little feedback (with
Best Ever Banana Cake With Cream Cheese Frosting as an example):
The metric conversions are really awkward, and it makes the recipes pretty messy. I don't think there's a single soul out there who will be measuring out 354.88 ml of flour or 1.23 ml salt with that precision. It's like reading 1.5813 cups of flour or 0.00013 cups of salt. Cooking is more about a dash of this and a pinch of that, unless you're a scientist on the matter..
Measuring jugs typically has markings for every 100 or 50 ml, so how about rounding off to the nearest 10 ml? Like 350 ml (for 354.88 ml), which is what you'll see in cookbooks? Same with weight in grams. Teaspoons and pinches are seldom given in ml, so I would also suggest to you to keep them as they are. It's common for cookbooks to write 1/2 teaspoon, topped tablespoon, and so forth.
Keep it up!
