4 oz. almonds, 1 T rice flour, and 1 1/4 C liquid are good proportions.
Pulverise almonds in a blender (not a food processor) or in a coffee or nut mill. Put them in a bowl and pour on enough boiling liquid to make a smooth cream. Leave to stand for 10-15 min., then rub the mixture through a metal sieve.
If this is not smooth enough, cream a little rice flour with it and heat until it thickens slightly. Add any extra liquid, and a scrap of salt.
Powder fort: 1/3 t ground cumin, 1/8 t black pepper, 1/8 t ground ginger
1 egg, separated, and 1 egg white
6-8 sheets file or strudel pastry
Powder douce: 1/8 t ground coriander, pinch of ground cinnamon, pinch of brown sugar
Mince the pork and set 8 oz. aside. Put the remaining in a bowl and add the salt, currants, and powder fort. Beat the egg yolk and use it to bind the mixture.
Stack the pastry sheets in a pile, making sure they separate easily. Beat the egg whites and use to brush the top of the sheet pastry lightly. Starting from one short side, cut it into long strips 3″ wide. Place a small tsp of the pork mixture on the end of one stirp and roll up like a Swiss roll. Press the ends to seal in the meat. Repeat with all strips, brushing each new sheet with egg.
Drop the rolls, a few at a time, into gently boiling salted water and cook 5-7 minutes, then drain on kitchen paper. Alternatively, place rolls side by side on a baking sheet, brush with egg white, and bake in pre-heated oven at 400F for 10-12 minutes; then serve them as snacks without sauce.
Boiled rolls need sauce: Heat stock and add reserved meat and powder douce. Simmer for several minutes to heat the meat through, and serve over rolls.
