Ingredients For the sausage roll 1 onion 30g/1oz butter 1 bay leaf 4 sprigs thyme, picked 1 sausage-style black pudding 250g/9oz puff pastry 1 egg, beaten For the sauce 100ml single cream 2-3 tsp wholegrain mustard 2-3 tsp Dijon mustard 1tbsp chopped parsley Preparation method Preheat your oven to 200C/400F/Gas 6. Roughly chop the onion and cook in a pan with butter, thyme and a bay leaf on a very low heat. This will help develop a lovely deep sweetness, so let them caramelise for a good 15-20 minutes. Roll out the puff pastry to 25cm x 20cm/10in x 8in sheet and 5mm/¼in thick on a floured surface. Lay a bed of the onions in the centre lengthways, roughly the same shape as the black pudding, place the sausage on top, and then any remaining onions on top again. Now egg wash the outline of the whole pastry sheet and simply fold one side over the other and crimp the edges. Neatness isn’t a priority; just make sure you form a seal. Then it’s in to the oven for 20 minutes. In the meantime prepare this wonderfully quick mustard sauce by heating up the cream in a saucepan and little by little add both mustards testing it as you go till it suits your taste. Finally finish off with some chopped parsley and trickle it over the black pudding sausage roll when it emerges from the oven.
