Week 3: The terminal of the global supply chain: the erasure of locality

Module 1 — Disenchantment.

The domestic refrigerator is the final two cubic feet of an infrastructure that spans oceans. Refrigerated shipping, rail, warehousing and air freight together form the cold chain, and your kitchen is its terminal — the last mile, where a system built for commodity trading delivers into a domestic appliance.

The consequence is that a temperate city eats Chilean cherries in July and Norwegian salmon on a Tuesday, and does so without anyone experiencing this as remarkable. Seasonality has not been overcome so much as abolished as information. A cook who can obtain any ingredient in any month no longer needs to know what grows when, what travels, what to do with a glut, or what a place tastes like at a particular time of year. That knowledge did not become wrong; it became unnecessary, which is a more permanent kind of loss.

The ecological accounting is the part that is hardest to see from inside a kitchen. Refrigerated transport and warehousing are energy-intensive at every link, the refrigerant gases are themselves potent greenhouse contributors, and the whole apparatus exists to move perishable goods further than they could otherwise go. The fridge’s promise of abundance has a carbon footprint that is charged to everyone.

Inherits from week 2: the household’s planning work was reorganised around a box that is always full. This week asks what fills it, and what had to be built.

Outline#

• the cold chain as infrastructure: shipping, rail, warehousing, air freight
• the kitchen as last mile of a commodity system
• seasonality as information, and the cost of abolishing it
• “freshness” as a manufactured category rather than a description
• the ecological ledger: energy, refrigerants and food miles

Reading#

• Susanne Freidberg, Fresh: A Perishable History (2009) — introduction and one commodity chapter of your choosing
• Nicola Twilley, Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves (2024) — the cold chain chapters

Pick your Freidberg commodity chapter in advance and pick one nobody else will — the tutorial pools them.

Tutorial preparation#

The tutorial builds a food-mileage map and requires photographs taken before Wednesday.
