Step 1

Soak the raisins in the rum for a couple of hours or overnight. Cover with plastic wrap and toss the raisins in the rum several times while soaking.

Step 2

Add the soaked raisins to a pot with the 1 cup water. (If not using the rum use 1 1/2 cups water, there is no need to pre-soak the raisins in water but you can if they are particularly dry. See note below)

Step 3

Slowly simmer for 5 minutes over low heat.

Step 4

In a separate saucepan combine the brown sugar, flour, milk, butter, salt, cinnamon and nutmeg.

Step 5

Cook this mixture over medium low heat until it thickens, stirring constantly. (see video)

Step 6

When thickened, add the raisin mixture & vanilla. You can add a couple of extra tablespoons of rum at this point if you like.

Step 7

Cook for another minute or two over low heat, then set aside to cool completely.

Step 8

Using a food processor or a pastry blender cut cold butter into flour, brown sugar and salt until mixture resembles a coarse meal. Small pieces of butter should still be visible.

Step 9

Pour the vinegar into ice cold water then pour over the mixture and work in by tossing with a fork until dough begins to form. Use your hands as little as possible and work the dough as little as possible.

Step 10

Divide dough into 2 balls, flatten into 2 rounds, wrap in plastic wrap and place in the refrigerator to rest for a minimum of 20 minutes. You can make your dough the previous day but make sure you take it out of the fridge for 10 minutes to warm slightly before rolling out.

Step 11

Roll the dough into a 12 inch round and place in the bottom of a 9 inch pie plate. Push the dough into the corners and ensure that it is not stretched at all or it will shrink from the edge. Trim dough to edge of plate.

Step 12

Pour filling into the bottom crust.

Step 13

Roll the remaining dough round into 12 inch square-ish shape and cut that into 8 equal strips for the lattice crust top.

Step 14

Add the lattice top and tuck the ends of the dough under the edge of the bottom crust. Crimp edges. Lightly brush with an egg wash if you like. I did.

Step 15

Chill the pie in the fridge for about 20 minutes to a half hour before placing it in a preheated 375 degree F oven.

Step 16

Bake for 45 minutes at that temperature. (Cover the edges of the pie with strips of aluminum foil to prevent them from burning if they are getting too brown. You can decrease the oven earlier if they brown quickly too.)

Step 17

Reduce heat to 350 degrees F and bake for an additional 15 minutes or so or until the top crust is a nice golden brown.

Step 18

Allow to cool on a wire rack at room temperature for at least a couple of hours before serving.

Step 19

NOTE: If your lattice crust begins to get too brown after you have covered the edges with aluminum foil but before the filling is bubbling, you can place a sheet of aluminum foil over the top during the last of the baking time if needed.
