Adapted from https://www.ainsley-harriott.com/recipe/tamarind-allspice-ginger-glazed-ham-with-pineapple-rum-relish/

3 cm root ginger, grated; 1 medium-hot red chilli, deseeded and finely chopped; 1 tsp mild curry powder; 2 star anise; ¼ tsp ground cloves; 125g light soft brown sugar; 100ml apple cider vinegar; 2 tbsp spiced rum (or orange juice); 1 medium-large pineapple, peeled, cored, and flesh chopped into 1 cm chunks, reserve any juice; 40g sultanas; zest of 1 orange; ½ tsp sea salt

Heat 1 tbsp oil in a saucepan over a low-medium heat and fry the ginger and chilli for 30 seconds until fragrant. Add the spices and cook for a minute. Add the sugar and stir, cooking until dissolved. Increase the heat and pour in the vinegar and rum and let it bubble for a minute. Add the pineapple and any of its juice, sultanas and orange zest. Season with the salt and bring up to a boil.

Reduce the heat to medium-low and simmer, stirring occasionally, for 40-50 minutes or until reduced and jammy but still with plenty of texture. Remove from the heat and allow to cool.
