100 attempts, need advice.

I'm tired of failing and need some advice.

A proper machine is showing up at my house this week and I'm putting a cow in my backyard for unlimited milk. I can spend the hours practicing but I don't think I can afford the 1000kg of beans I'm going to need to level up.

Can I pour into water with food coloring or somethong else? Chocolate milk maybe? Instant coffee?
