These jelly-filled doughnuts are made to celebrate Hanukkah. You can substitute shop-bought jam for the jelly. You'll need to begin this recipe a day ahead.
Note To test setting point, place a few saucers in freezer while jelly is cooking. Remove jelly from heat and spoon onto a cold saucer, return to freezer for 30 seconds, then push with your finger. If it wrinkles, it's ready. If not, cook jelly for another few minutes, test again, remove from heat and set aside to cool.
