Pecan Pralines

3 cups granulated sugar
1 cup packed brown sugar
1 1/2 cups water
3 cups chopped or halved pecans
1 tablespoon butter
1 teaspoon vanilla extract
In a large, heavy pot combine sugar, brown sugar and water; bring to a
boil. When sugar is dissolved, add pecans. Reduce heat and gently
simmer, uncovered, stirring occasionally. Cook for "about 15 to 20
minutes, until the mixture grains when metal spoon is rubbed against
side of pot" (direct quote from original copy). Remove from heat.
Add butter and vanilla. Beat mixture with wooden spoon until it appears
to granulate and adhere to the spoon. Drop by spoonfuls onto waxed paper
or foil. Cool completely.
Note: This is what pralines really tasted like in the 1800's. Most of
today's pralines have milk in the recipe and are not authentic in taste.
If candy does not set, return to pot and cook longer. If is hardens
before you can drop it, add a little more water and bring to a simmer.
