This is the best sausage roll I have ever had! But first of all ,you have to make the sausage. In Scotland this sausage is called by many names, you can call it square sausage, flat sausage, square slice or Lorne and this all-beef steak version is the king. A helpful butcher suggested to use ‘outer’ fat so you will need to get that from your butcher.
Makes approx 14 square slices
1kg Beef Flank steak (you can get your butcher to mince it for you)
200g Beef fat/outer fat, minced
100g fine breadcrumbs (I used panko and blitzed them to a fine crumb)
175ml cold water
Half tsp carmine extract powder (cochineal) is optional but retains the red colour
2 tsp salt
1 tsp each of ground mace, nutmeg, coriander, white pepper, black pepper, cayenne pepper
Mix it all well together then press it into a plastic wrap lined loaf tin, 22cm x 11cm x 7cm, using your hand and a spatula to get it well compressed. Cover it over with the plastic wrap and chill for at least two hours, I left mine overnight. Cut it into slices, I found a bread knife worked the best! Freezes really well once sliced, drop a little piece of greaseproof paper between each slice for ease of separating!
Makes 6 Square sausage rolls
1 x pack rolled puff pastry (I use @careme) divided into 6
6 slices square sausage (homemade or butcher bought)
Approx 2 tsp Dijon mustard
2 small brown onions (or one large)
1 tbsp Scottish whisky
1 tsp light brown sugar
Finley slice your onion and soften in olive oil, when soft add your whisky and let the alcohol bubble off, then stir through your brown sugar over the heat for a few minutes. Leave to cool.
Divide your puff pastry into 6 strips to fit your sausage. Divide the onions between the pastry strips and shape into the rough size of the sausage. Brush each slice of sausage with Dijon mustard and lay mustard side down on the onions. Fold over your pastry and seal with an egg wash. Place square sausage rolls seam side down on a baking sheet, egg wash tops and get into a preheated fan oven at 180c for 30 mins until golden and delicious.
Remove to a wire rack to cool a little and serve. I served mine with a beer and homemade brown sauce.
