For best results, use room-temperature ingredients so the sponge stays light and airy, and avoid overmixing once the flour is added to keep the cupcakes tender. If the ganache becomes too runny, chill it briefly, stirring every few minutes until it reaches a spreadable consistency; if it thickens too much, warm it gently over a pan of hot water. You can adjust the orange intensity by adding extra zest to the batter or a splash of orange extract to the ganache, and if you cannot find block jelly, a small spoon of firm-set orange jam in each cupcake works well. Store the cupcakes in an airtight container in a cool place for up to two days, and for the cleanest finish, dip your knife or spoon in hot water and wipe dry before smoothing the chocolate tops.
