If your gammon is smoked like mine place it in a pot filled with water and bring it to the boil. Discard water after then we can start.

Place the gammon and pour the Coca Cola, add the onion halves and bring to boil then reduce to a simmer for 2 hours. Once cooked discard the Coca Cola. (Preheat the oven to 230 degrees.) Cool down the gammon. Remove skin with fat under and score the gammon fat.

For glaze. In an uncovered pot mix sugar and water and heat it up. Once it boils add mustard and stir. That’s it. Using half the glaze pour over “cloved” gammon. Place in oven for 10 minutes and pour rest of mixture and return to oven.

Rest gammon for 10 minutes before cutting and serving 😍
