Cut Your Grocery Bill Without Eating Worse: A Practical Market Guide

A French household spends around $440 to $660 a month on food for two people, depending on habits. A good part of that money goes either to purchases you didn't need or straight into the trash: people in France throw away an average of about 66 lb (30 kg) of food per person per year, roughly $165. Before looking for cheaper products, there are structural losses to fix.

Get to the market late in the morning

Open-air markets close between 1 and 2 p.m., depending on the town. In the last 30 to 45 minutes, growers mark down whatever they don't want to carry back. Tomatoes at about $0.40 a pound instead of $1.25, leeks at half price by the bunch. They'd rather sell at a loss than haul it home and throw it out. It isn't true of every stall, but at a mid-sized market you'll always find a few vendors marking things down. The quality is exactly what it was in the morning: the vegetables have simply spent a few more hours on the table.

“Ugly” vegetables: same nutrients, different price

For some years now, supermarkets have had “ugly vegetable” sections: crooked carrots, cracked tomatoes, double zucchini. Nutritionally, there's no difference from a standard graded vegetable. Price-wise, it's often 30 to 50% lower. For a soup, a ratatouille or a gratin, the shape of the vegetable doesn't matter at all.

Dried legumes vs. canned: the real math

Dried French green lentils (Puy) cost about $1.25 a pound ($2.75 a kilo) at the supermarket. 3.5 oz (100 g) dry makes about 8.5 oz (240 g) cooked, a generous serving. One kilo (2.2 lb) dry is 10 servings, so about $0.30 per serving. A can of lentils (14 oz or 400 g, about 8.5 oz or 240 g drained, which is 2 slim servings) costs $1.30 to $1.65, or $0.65 to $0.80 per serving. Dried lentils therefore cost about 40% of what canned ones do, provided you plan ahead for the soaking (30 minutes for red lentils, overnight for chickpeas) and the cooking (20 to 40 minutes depending on the variety).

The caveat: cans have their place on nights when you haven't planned anything. But if you cook legumes regularly, buying dry and cooking a big batch on the weekend for the week pays off and is simple.

Organize the fridge by temperature zone

The coldest part of the fridge is the bottom (32 to 40°F, or 0 to 4°C). That's where fresh meat and fish go, since they need the coldest spot to avoid spoiling quickly. The crisper drawer (the humid drawer, at the bottom or top depending on the model) keeps humidity high, which keeps leafy vegetables crisp 3 to 4 days longer than loose on a shelf. Dairy and leftovers go in the middle. The door is the least cold zone: use it for condiments, juice and eggs, not for perishable foods.

The “noble leftovers” rule

A Sunday roast doesn't have to end up reheated in its juices on Monday. Cold, sliced thin, it makes a sandwich with mustard and pickles that's as good as any ham. The carcass plus the vegetables from the pan go straight into a pot with 1.5 quarts (1.5 liters) of water for a broth that lasts 48 hours (2 days in the fridge). That broth becomes a soup on Tuesday night with the week's leftover vegetables. It's a week of cooking from a single purchase of meat.

Smart freezing

Sliced bread freezes as is and goes from the freezer to the toaster with no thawing: 3 minutes and it's hot. Fresh herbs (parsley, basil, chives) freeze chopped in ice cube trays filled with olive oil. Drop one or two cubes straight into the pan. Ground meat freezes in flat 5 oz (150 g) patties in individual bags: it thaws in 20 minutes at room temperature, no microwave needed.

DLC vs. DDM: the difference few people get

The DLC (date limite de consommation, a use-by date) is printed on meat, fish and pasteurized fresh products. It signals a real health risk after that date. You don't gamble with it. The DDM (date de durabilité minimale, formerly “best before”) is printed on dry goods, yogurt, canned food, pasta, rice and coffee. It doesn't signal a health risk, only guaranteed peak quality. A yogurt two weeks past its DDM is still fine. So is pasta a year past it. Knowing the difference keeps you from throwing out dozens of dollars of perfectly edible food every month.
