I wanted to make something with the soft pastry that a Linzertorte has, but without the nuts. My daughter, visiting for a few days, has a severe peanut allergy which, when first diagnosed, made her wary of eating any nuts. Although we don't think she's allergic to any of them she still prefers not to eat them - cross contamination is often a risk.
I also wanted to do something to preserve the last of the strawberries until she was home, and have always wanted to cook rhubarb and strawberries together. In the end I made a small batch of jam with 350g rhubarb and 150g strawberries, but I think this was too sweet - I should have just cooked the fruit with sugar to taste to make a thick compote. I also didn't cook it enough to give a good set - it was too soft, even after cooking it again in the tart.
For the pastry I used 250g SR flour, 150g butter, 50g icing sugar, 1 egg and water as required to mix to a soft dough. I added the zest of a large orange, a quarter of a teaspoon of cinnamon and a grating of nutmeg to give some of the flavouring of Linzertorte pastry.
Unfortunately the sweetness of the jam overwhelmed any other flavour, and because of the small proportion of strawberries used it was difficult to judge whether rhubarb and strawberries used together is better than either of them used separately.
