Solo Living
Easy-to-use, affordable, and quick-to-cook ingredients for one
When living alone, choose pre-cut large vegetables like cabbage and daikon, or use freezing to consume them without waste. Keeping cherry tomatoes and broccoli on hand — ingredients that are ready to eat after a quick rinse or a brief boil — lowers the barrier to home cooking. Frozen fish fillets (saba, salmon), shirasu (baby sardines), and salt-cured seafood can be used in small amounts too. Long-lasting onions and frozen spinach you can use as needed are reliable allies to always have in stock.
