The recipe I have has an egg, but here's a recipe that doesn't (I found it on the internet a few years ago - I've never tried it).

3 cups sugar
1 cup water
5 cups ground almonds
1 tsp or more of almond extract (to taste)
Food coloring of various colors

Dissolve the sugar and water in a saucepan and add the almonds.

Cook on low heat, stirring constantly, until the marzipan comes away from the pan.

Remove from heat and turn out onto a baking sheet.
Knead until smooth, adding extract while mixture is still warm.

Divide up the marzipan, adding food coloring to each part to shape into any variety of fruits, vegetables.
