Nobody likes soggy pancakes, and putting them on a plate and covering with foil or a tea towel will deifnitley make that happen! The best way to keep your pancakes warm while you cook the rest is to heat your oven to 200f/100°c or warming setting if you have it. Place the cooked pancakes on a wire cooling rack on a cookie sheet or baking tray inside the warm oven. The cooling rack allows air to circulate so the pancakes don't get soggy!
