Batch cooking in a shared kitchen
Tell roommates when you need the kitchen for a large cook. Pick a lower-traffic time, clear your supplies first, and leave enough counter and sink space for someone else to make a meal.
Use containers that stack and label them with a date. Keep your food within your assigned fridge and freezer space; batch cooking is helpful only if it does not displace everyone else.
Clean as you go and finish with the sink, stove, counters, and floor. The batch is yours; the cleanup is too.
