Set aside to dry for 20-30 minutes. Again, this completely varies. I've found that if the batter is towards the looser side, then it takes longer to dry and if it’s thicker, it will dry in about 15 minutes. Humidity also slows the process of drying. To test, lightly touch the piped batter with your little finger and if it sticks, that means you need to leave it longer. If it’s slightly hard and dry, then you are good to go. If you don't let it dry enough, your macarons won’t come out with good ‘feet’
