Nuts and dried fruit travel well if you protect them from heat and moisture, which is what Habbitree’s storage advice is about.
Portion 30 g servings into small airtight containers.
Keep them away from direct sunlight and moisture.
Reseal the main pack after each use.
Use a dry spoon or clean, dry hands.
Good travel choices include whole almonds, cashews and roasted pistachios (each best before 9 months) and Black Kishmish (18 months). For tree-nut-free company, bring seeds instead, though their packs are made in facilities that also handle nuts.
