Best Long-Life Emergency Foods from UK Supermarkets
How to build a high-calorie, nutritionally balanced 14-day or 30-day UK emergency pantry from Aldi, Lidl, Tesco, Sainsbury's, Asda, or Morrisons — and track every expiry date automatically.
The "Store What You Eat, Eat What You Store" Rule
The most common mistake in household emergency preparedness is buying expensive specialist freeze-dried buckets that nobody in the family enjoys eating. By stocking everyday UK supermarket tins, grains, and fats — and rotating them using FIFO (First-In, First-Out) expiry sorting — your emergency reserve costs nothing extra over time because every tin is eaten before its Best Before date.

Balance Ready-to-Eat vs. Dry Staples
A 5kg bag of dried rice or pasta contains over 17,500 kcal, but it is inedible during a winter power cut unless you also have cooking water (+0.8L/person/day) and cooking fuel (Campingaz CP250 cartridges, Calor Gas butane/propane, or wood).
PrepTrack's Dietary Balance & Hardware Checks automatically warn you if your food reserve relies on dried staples without a stove/fuel, or if your protein/fat balance is too low.
Track Multiple Pack Sizes & Expiries (FIFO)
In a real UK kitchen cupboard, you might have 8 × 400g tins expiring in November 2027 and 4 × 415g tins expiring in March 2028 across two locations (Kitchen Cupboard and Loft).
PrepTrack groups identical products into a single cumulative total while sorting individual stock lines by earliest expiry date first (FIFO) so you always use the oldest tin next.
