Step 3: Fold the ground almonds and flour into the mixture with a spatula. Don't forget to lick it!
Step 4: Heat your oven to gas mark 4, 180 degrees, 160 degrees fan.
Step 5: Spoon the frangipane into the pastry base, smoothing the surface. Half, pit and then slice the plums into eighths. Then arrange the plum slices, slightly overlapping, over the top, pressing slightly into the frangipane. I think I could have actually used more plum slices because they do shrink a little once baked, so don't hesitate to really pack them in! I also think it might be good to sprinkle some sliced almonds on top before baking - I think I'll do this next time to add some crunch.
Tesco, which where I found this recipe!
