The choice of apples is debatable but I would go for hard apples that do not give rise to a compote when cooked, so either granny smith or greenish golden apples. Also you need a nice tarte Tatin form that can go both on a hot plate and in the oven (avoid spring forms as caramel can easily leak out from edges). I hope you enjoy this recipe, it is one of my favorites, and I would say this tarte Tatin is even better than the one I was taught to make :-)
Recipe for the tarte Tatin (28 cm)
Shortcrust dough:
240 g flour
salt
sugar
137 g butter
1 dl cold water
Mix flour, sugar, salt. Cut cold butter in pieces, add to flour and mix with your fingers to make crumbs. Add cold water and mix fast with a wooden spoon. Make the dough, cover and refrigerate it 30 min.
12-15 apples
(I have tried and liked Gala and Pink Lady apples, Boscoop apples are not good here but rather for compote, and Granny Smith apples are too hard and sour)
Peel apples and cut them in 2 (in quarters if you prefer).
Caramel:
150 g butter
300 g sugar
Place sugar and pieces of butter in a Tatin form. Place the form on a warm plate and let sugar and butter melt on medium/high heat (3-4/6). Mix with a wooden spoon until obtaining caramel: remove the form from the heat source when you are happy with the color. Note: it will go from light yellow when melting to amber color when sugar fuses, to light brown when the caramel starts forming: then it only gets darker with time. I like a real brown color such that apples will have that color once baked (but if you let your caramel darken too much it will become bitter).
Place apples really tight together (vertically) on the caramel in the Tatin form (and fill possible holes in between apples with more apples because when they bake apples shrink and you don't want random empty spaces in your tart). Put the form back on the fire and let apples bake and get impregnated with the caramel for 7-8min on high heat (5-6/6). Put aside and sprinkle the apples with some cinnamon.
Roll out the dough on a floured table (approx 4 mm thick) and transfer onto the Tatin form on top of the apples. Fold in the edges of the dough such that it does not go on the form itself. Bake in the oven 35 min at 180-200 C. Flip the tart over when still warm (else the apples will stick to the form).
Serve lukewarm as is or with a scoop of vanilla ice cream, I think it is even better :-D Enjoy!!!
