For the honey corn muffins, preheat the oven to 180 °C.
Grease the muffin tin and sprinkle with cornmeal.
Soak the raisins in the rum.
Mix the flour and cornmeal with the baking powder and baking soda in a bowl. Add the salt.
In a second bowl, beat the egg briefly and mix it with the buttermilk, honey and oil.
Pour the raisins into the egg-buttermilk mixture.
Quickly stir the flour mixture into the egg mixture. This is best done with a fork. Do not stir too long or the muffins will be hard and tough.
Pour 2/3 of the batter into the ramekins, leaving room for the mixture to rise.
Bake the honey corn muffins on the middle shelf for about 20 minutes.
