This is a crumble of dreams. This is nothing short of alchemy: you take the vilest, crunchiest supermarket strawberries, top them with an almondy, buttery rubble, bake and turn them on a cold day into the taste of English summer. Naturally, serve with lashings of cream: I regard this is as obligatory, not optional. For this recipe you will need 1 ovenproof pie dish approximately 21cm/10in diameter x 4cm/2in deep (approx. 1.25 litre/2 pints capacity).
