What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use old-fashioned rolled oats, not instant, for the best chewy texture in the crumble.
- 2Chill the bowl and your hands if the butter starts to soften while cutting in — cold butter is key for crispy clusters.
- 3If your coconut sugar has hard lumps, sift or whisk it to break them up before mixing.
- 4For an extra-crunchy topping, refrigerate the finished crumble for 15 minutes before baking.
- 5Store unbaked crumble in the freezer for up to 3 months; bake directly from frozen without thawing.
- 6Do not overwork the butter — stop once the mixture looks like coarse, clumpy wet sand with no dry patches.
