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)
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.
* Marzipan vs. Almond Paste - the difference: Almond paste is softer and is used in baked goods. Marzipan is firmer and is used in making candies/chocolates or as fondant for cakes. Marzipan also includes rose water. To adjust this recipe according to what you're using it for, follow this recipe as instructed for almond paste (I still include the rose water because it tastes amazing), or if you're making marzipan add an extra 1/4 cup or more of almond flour until you reach a firmer consistency (one that you can roll out with a rolling pin without it sticking).
