Step 1 of 4

Make the patties wider than you want them

Mix the sausagemeat with the fennel seeds, salt and pepper, divide it into four and press each one into a thin patty about a centimetre wider than a muffin.

— They shrink and dome as they cook. A patty made to fit the muffin comes out a thick disc two-thirds the width, which is how a sandwich ends up all bread at the edges.
