Think cheese on toast, but somehow richer and lighter, if one thing can be both. Gill uses really good strong Cheddar cheese and some punchy English mustard. The egg yolks get folded into the cheese mixture, which gives it a lovely richness and depth, and the egg whites are whisked and gently folded in, giving the rarebit a wonderfully light, almost soufflé-like texture when it comes out of the hot oven. It’s a lovely thing to make for breakfast or brunch, or as a snack after a day gardening.
