Heat oil in a large nonstick skillet set over medium-high heat. Add apples, onion, garlic and ginger. Cook, stirring often, for 5 minutes or until softened. Add rosemary, cinnamon, allspice, salt, pepper and cloves. Cook for 3 minutes or until fragrant. Add brown sugar, water, vinegar and raisins; bring to a boil. Reduce heat and simmer, stirring occasionally, for 8 to 10 minutes or until thick and most of the liquid has evaporated. Stir in grainy mustard. Cool to room temperature.
TIP: Add 1 tablespoon of brandy when adding the brown sugar to the chutney for an even richer flavor.
