1 1/2cupsvery finely ground blanched almond flour/meal, or blanch, grind and dry your own almonds - I recommend the bought almond meal to ensure it's finely ground and sufficiently dry
1egg white(if you can't find pasteurized eggs and that is a concern to you, you can substitute liquid pasteurized egg whites or reconstituted powdered egg whites) (vegans: use egg substitute or 4+ tablespoons corn syrup, golden syrup, or other liquid sweetener)
Instructions
Place the almond flour and powdered sugar in a food processor and pulse until combined and any lumps are broken up. Add the almond extract and rose water and pulse to combine. Add the egg white and process until a thick dough is formed. If the mass is still too wet and sticky, add some more almond flour. Keep in mind that it will become firmer after it's been refrigerated.
Turn the almond marzipan out onto a work surface and knead it a few times. Form it into a log, wrap it up in plastic wrap and refrigerate.
Will keep for at least a month in the refrigerator or up to 6 months in the freezer. Bring to room temperature before using in any recipe.Makes 13-14 ounces.
Notes
To make a firmer Marzipan that you can shape into figures for decorations, add 1/4 cup or more of sugar until you reach the desired level of firmness (keep in mind it will also become firmer after it refrigerates).
