Dry or semi-dry foods like rice, roti, dry vegetables, and sweets can be layered in a tiffin without mixing, provided each layer is reasonably compact and doesn't contain excessive liquid.
When packing a tiffin, the key is to prevent liquids from seeping between layers. Foods with minimal moisture content are ideal for layering. Here's a breakdown:
Rice: Cooked rice, especially if slightly cooled and not overly sticky, works well as a base layer. Ensure it's not swimming in sauce.
Roti/Chapati: These flatbreads are inherently dry and can be stacked on top of each other or used as a divider between other foods.
Dry Vegetables: Vegetable preparations like stir-fries (e.g., aloo gobi, bhindi masala) that are relatively dry and not gravy-based are suitable.
Sweets: Dry sweets like barfi, ladoo, or peda can be included without causing significant mixing. Avoid very syrupy sweets.
Snacks: Items like dry cutlets, pakoras (if not oily), or mathri can be layered.
Avoid layering foods with significant sauces, gravies, or liquids directly on top of other items unless you have a tiffin with completely leak-proof compartments.
Use parchment paper or aluminum foil as a barrier between layers, especially if you're concerned about slight mixing or flavor transfer. This is particularly helpful when packing foods with strong aromas.
