Mexican Nut Candy

Stir both of the sugars, milk and margarine together in a large pan.

Cook over a medium heat, stirring occasionally, until the mixture forms a soft ball when a little bit of it is dropped into a glass of cold water.

(It is too soft if the mixture covers the bottom of the glass; it should hold together loosely.)

Add the vanilla and salt; cook about 1 minute longer.

Remove from heat and add nuts.

Beat with a spoon until candy starts to get very thick (a wooden spoon is best).

Drop by large spoonfuls onto wax paper. Let cool.
