Ale, apple and mustard chutney is a tangy, deeply flavored preserve that makes excellent use of tart cooking apples. The combination of brown ale, malt vinegar, and crushed mustard seeds creates a robust condiment with a complex, sweet-and-sour profile. It requires minimal hands-on effort, needing only an occasional stir as it slowly reduces on the stove. Serve it alongside cold roast beef, thick slices of ham, or sharp cheddar cheese to instantly upgrade your lunch sandwiches.
