What to use inplace of milnot?

Milnot is a canned evaporated milk product, so you can substitute it with an equal amount of regular evaporated milk or a mixture of half milk and half cream for a similar richness and texture. If you're looking for a dairy-free option, coconut milk or almond milk can work, though they may alter the flavor slightly. For a thicker consistency, you could also blend silken tofu with water to reach the desired texture.
