Kasia's Apricot and peach shortcake

[oli]

Below is her recipe and I need some help. I understand blancmange is vanilla pudding in the USA and how much vanilla pudding do I use in place of her 2 packets of blancmange? In my area apricots are just out of season so can I use dried apricot and just rehydrate?

 

 

"Fortunately, the summer is not only about the weather. There is also fresh, sweet-smelling fruit. Today I would like to share with you the recipe for an easy to make weekend cake. It is excellent for afternoon tea or coffee. A little work and a little baking and after that you may serve and eat, and serve and eat again and again ... I remind you that it should be a weekend cake, so if you eat everything at once, you will need to bake another one 

Ingredients:
dough
200g of flour
150g of butter
75g of sugar
1 egg
1 egg yolk
1 teaspoon of baking powder

fruit:
1kg of apricot
4 peaches
2 packets of powdered vanilla blancmange
4 tablespoons of brown sugar

Put the flour, sugar, baking powder and butter onto a baking board. Chop it all up with a knife. When you have the consistency of crumble topping, add the egg and egg yolk and then knead the dough quickly. Divide the dough into two parts – 2/3 and 1/3. Cover the pieces of dough with plastic wrap and put them into the freezer.
Wash the apricots, remove the stones and cube them. Put them into a saucepan, add a bit of water and boil until they are soft. Stir the blancmange powder in 150ml of cold water and add it to the apricots. Boil for 2 minutes stirring constantly. Turn off the heat. Wash the peaches, remove the stones and cube them. Add them to the apricots and mix them in.
Heat the oven up to 180C.
Smooth a 23-cm cake tin with some butter and sprinkle with breadcrumbs. Grate the bigger part of the dough onto the cake tin, even it out and bake for 15-17 minutes. Take out the cake, but don't turn off the oven. Put the fruit mixture onto it and grate the rest of the dough onto the top. Bake for 50 minutes. Sprinkle with caster sugar before serving."

You can get blancmange packets via amazon! Personally I would go with all peach (or sub for nectarine) instead of using dried apricot, I don't think they'll ever get as soft as you want for this recipe. Just my .02c
