Every JustAddFlavour Spice Pack, contains either dry ingredients such as Cinnamon Powder, or liquid ingredients such as Soy Sauce, which means our product has a long perishable date. Customers have the option to use soon after purchase, or leave it in the cupboard for that day when they want something both quick & easy and tasty & full of flavour. Each Spice Pack is heat sealed to maintain freshness and quality. Each pack contains a very detailed recipe card, with a recipe timeline explaining exactly when each task should be performed and in what order. Also the recipe card has very detailed pictures, so you not only know exactly when to do things, but thanks to the pictures you'll know exactly how to do things. Recipe card also contains nutritional facts, shopping list and other recipe info.
