Spare Spoons Kitchen
A free-form tart that plays to firm fruit — the slices stay distinct and just barely soften in the oven. No pie dish, very forgiving.
The number-one galette failure is a soggy bottom from too much juice. Macerate the fruit, then lift it out with a slotted spoon and leave the pooled liquid behind. The cornstarch sets whatever juice clings to the slices.
Firm fruit is an advantage — it sheds less liquid than soft fruit would. Slice it a touch thinner (about ¼ inch) so it cooks through in the open center.
Keep everything cold for a flaky crust — dough, butter, even the bowl. If the kitchen is warm, chill the shaped galette 15 minutes before it bakes.
The roll-out size and number of rounds update with the slice count, holding the crust at about ⅛ inch: it stays a single galette through 9 slices, then splits into two so no round outgrows a half-sheet pan.
Don't rush the cool. The juices are liquid straight from the oven and need the rest to set into something sliceable. A spoonful of the reserved macerating juice, reduced in a small pan, makes a fine glaze if you skip the jam.
Vegan / dairy-free: use cold vegan butter (a block, not a soft spread) in the dough, kept cold; brush the crust with plant milk + a little maple syrup (or aquafaba) instead of egg wash for browning. The fruit filling is already vegan.
Gluten-free: a 1:1 GF pastry blend (one with xanthan). Chill well and handle gently — GF dough is more fragile and less forgiving of rerolling.
