Jam's bitter cousin that refused to apologize for the peel.

means A citrus preserve made from the fruit's pulp, juice, and especially its peel, cooked down with sugar until it sets into something glossy and a little sharp.

from Traces back through French 'marmelade' and Portuguese 'marmelada', which named a quince paste — from 'marmelo', the Portuguese word for quince. So the word originally belonged to quince jam entirely; the leap to orange marmalade came later as the term drifted to cover citrus preserves generally, peel and all.
