I've been working on perfecting this tart, and I think I got it right. It's a flaky crust (pâte brisée) with orange frangipane cream. For the frangipane, I used 7 oz. butter mixed until creamy, and then creamed it with 7 oz. sugar (in two additions) and some salt (the basic recipe is Tartine's). To this I blended in 7 oz. of almond flour. I added the zest of one orange, 1 tbsp. brandy, 1 tbsp. orange flower water and one egg. Blend well, add a second egg and 1 tbsp milk. Spread in an unbaked, chilled tart mold (10 inches) and sprinkle with sliced almonds. Bake at 350º until set (≈45 mins) and glaze with the juice from the aforementioned orange reduced with 2 tbsp. apricot preserves.
This was really wonderful — and inspired by these orange blossom friands, which are also delicious.
