Heerenbone salad

1. Mix the ingredients and spread as thinly as possible onto a silicone baking mat or greaseproof paper.
2. Chill until slightly set, then cut into even rectangles. Store in the fridge, covered, for up to a week. If you’re layering them, place sheets of greaseproof paper between the layers.
Cook's note: You could crush the cereal in a food processor but there’s a lot of fun in doing it the old-fashioned way: place it in a bag and bash with a rolling pin. Once made, store the wafers in the freezer as they tend to become soft after about 30 minutes.
