I used to use these in the restaurant industry way back when, and I was curious if I could use for pancake and waffle batter. These are fantastic. I make a whole grain waffle/pancake and was worried it would be too thick to come through the valve. I was happy to find that this works great, even with the thick batter.I use these to make silver dollar pancakes and pancakes in shapes (hearts, emojis). This works very well. It is a soft plastic and squeezable and takes very little effort to use.I might load one of these with mayo and keep it in the fridge.Highly recommended!
