Glazed ham with pickled pineapple pizze

1.For pickled pineapple, combine vinegar, sugar and 50ml water in a bowl, season to taste and stir until sugar dissolves. Add remaining ingredients, transfer to a sterilised jar then refrigerate at least overnight. Pickle can be made up to a week ahead.

2.For pizza dough, combine, yeast, olive oil, sugar, ½ tsp salt and 350ml lukewarm water in a bowl, and set aside until foamy (2-3 minutes). Gradually add flour, mixing until a rough dough forms, then knead on a lightly floured surface until smooth and elastic (6-8 minutes). Place in a lightly oiled bowl, cover with plastic wrap and refrigerate overnight to rest. Bring to room temperature (2-3 hours), then knock back dough and knead on a lightly floured surface. Divide into 10 pieces, roll each into a 3mm-thick round, place on trays lined with baking paper and scattered with semolina, and refrigerate for up to an hour.

3.For spice-glazed ham, preheat oven to 180C. Simmer ingredients except ham and rosemary in a small saucepan until reduced a little (10-12 minutes). Place ham in a roasting pan, pour glaze all over, top with rosemary sprig and roast, basting occasionally (add a little water if glaze becomes too sticky), until sticky, golden and caramelised in places (1-1¼ hours).

4.To serve, preheat a kettle barbecue or char-grill pan to medium-high. Brush pizza bases with oil and grill in batches until charred (2-3 minutes each side; cover with foil if colouring too quickly). Top with mozzarella, sliced ham, pickled pineapple, tomato and herbs, cover with a lid and grill until warmed through. Serve hot scattered with grated parmesan.
