Return the milk and egg mixture to the pan and place on the stove over medium low. Using a silicone spatula or wooden spoon to gently stir and scrape the bottom and corners of the pan, cook until the sauce has thickened, an instant-read thermometer shows 170F, and you can scrape the back of the spatula through the sauce and leave a path that doesn't disappear. This should take about 4-5 minutes.
You can replace 1/4 cup or 40 grams of the all purpose flour with the same amount of almond meal or almond flour.
Make sure the apricots are ripe, but not over-ripe. Over-ripe will result in a wet, mushy apricot, instead of silky soft apricot once baked.
This is just enough vanilla sauce for serving with the tart. Honestly I would just double the recipe, it will get used, I promise!
The pastry and the frangipane (almond cream filling) can be made ahead and even frozen separately till ready to bake up. Wrap the pastry well in plastic wrap and then place in a freezer bag. The almond filling can be placed in a sealed container for freezing. Thaw in the fridge over night. Continue with the recipe.
