# Expert Advice:

01 -
  • It takes less than an hour from start to table, making it the perfect last-minute dessert that tastes like you planned it all along.
  • The contrast between tart berries and buttery, nutty crumble is honestly addictive, and somehow it feels elegant without being fussy.
  • It works with whatever berries you can find, so there's no excuse to skip it based on what's available.
02 -
  • Using frozen berries is absolutely fine and often tastes better because they're frozen at peak ripeness; just don't thaw them before using, as they'll release too much liquid and the filling becomes watery.
  • The cornstarch is crucial for preventing a soupy filling, but it needs to be mixed in with the berries before baking so it distributes evenly and thickens everything properly.
03 -
  • Keep your butter genuinely cold by cutting it into cubes and even chilling it for a few minutes before mixing if your kitchen is warm; this is the difference between a crumbly, tender topping and one that's dense and cake-like.
  • Don't be tempted to skip the lemon juice thinking the berries are already tart enough; it adds brightness that makes people say they can't quite put their finger on what makes this taste so good.
