Preheat the oven to 325ºF / 165ºC and grease an 11inch fluted tart tin with a removable base.
In a medium bowl mix together the cranberries, half a cup of sugar and the almonds. Transfer to the tart tin and sit on a baking sheet.
In a separate bowl beat the eggs, butter, extract and remaining sugar then beat in the flour until just combined. You will have a very thick batter.
Spread the batter over the berries and bake in the oven for 40-45 minutes until a toothpick inserted into the center comes out clean.
Cool in the tin. Store left overs in the fridge.
