# Expert Advice:

01 -
  • The contrast between the warm, jammy berries and the buttery, cinnamon-scented crumble topping creates an almost magical comfort that feels like a hug on a cold evening.
  • It strikes that perfect balance between effortless preparation and impressive results, making it ideal for both casual family nights and impromptu gatherings when neighbors drop by.
02 -
  • The filling will continue to thicken as it cools, so dont panic if it seems a bit loose when first out of the oven.
  • Adding just a small pinch of salt to the crumble topping dramatically enhances all the other flavors without making anything taste salty.
03 -
  • Work the butter into the crumble mixture just until it resembles coarse breadcrumbs with some pea-sized pieces remaining for that perfect texture contrast.
  • Let frozen berries thaw just slightly before mixing with other ingredients, which helps them release their juices while baking without becoming too watery.
