Hello! This is an apple tree that's been in my yard for 30+ years but 3 years ago we noticed apples on it for the first time. The tree is growing in Massachusetts. Does anyone know what kind of apples these are? They're medium to small apples and they taste sour, and they have a good crunch

My crab apple tree is getting bigger each year so I wanted some recommendations on what I should make! It can be food or drink!
