I can't remember when I opened the sesame oil

I found a half-full bottle of sesame oil at the back of the cabinet.

The printed expiration date had stopped sometime last spring. The day I opened it, of course, was written nowhere. It smelled less like oil and more like an old cardboard box, so it went down the drain.

That same afternoon, I emptied one shelf. Out came expired miso, hardened curry powder, a bottle of fish sauce I couldn't date. Seven bottles, in total.

This post is about what I've done since that day — only the parts that have stuck for three months. Strict spice-storage protocols and "use it all up by Sunday" plans aren't here. Those didn't last.

Why seasonings go bad without you noticing

Unlike vegetables, you can't really see when a seasoning has gone off.

Soy sauce just darkens a little. Miso dries at the surface. From the outside, they look the same as they did six months ago. Wilted spinach in the crisper drawer announces itself. A bottle of sesame oil sitting on a shelf does not.

Then there's the open-date problem. The label tells you the unopened shelf life, but most condiments lose their character within a few months once opened. The only person who knows when that was is you, and you don't actually know.

The third issue is uneven use. Soy sauce empties quickly. Oyster sauce and chili bean paste, the ones you reach for occasionally, sit half-full for half a year. Slow to empty doesn't mean fresh, but on a shelf, slow looks like "still got some."

What I stopped doing — date stickers, tracker apps, bulk buying

First I tried masking-tape labels with the open date written on each bottle.

They lasted two weeks. Tape doesn't stick to oily glass. The pen disappears by day three. New bottles never get labeled.

A dedicated expiry-tracking app lasted a week. Logging more than ten bottles is, frankly, not how a normal evening should go.

Bulk buying went too. I once bought a second sesame oil because it was on sale. Both ended up old. Buying cheaply and then throwing it away is probably the most expensive way to shop.

What stuck #1 — One shelf photo, once a month

On the first Sunday of the month, I take one photo of one shelf.

One more photo of the door pocket of the fridge. That's it. Trying to photograph everything is what kills the habit, so I keep it to a single shelf.

When I scroll back later, last month's photo sits next to this one. "That oyster sauce — it hasn't moved at all" becomes visible without effort. A bottle that hasn't moved is one I'm not using.

Whatever I notice, I use that week. Fried rice, a stir-fry, anything. The dish doesn't need to be impressive. The point is to move the bottle.

What stuck #2 — One rule: opened means fridge

Every seasoning has its own correct storage. Some at room temperature, some refrigerated after opening, some standing upright. I couldn't keep all of that in my head.

So I cut it down to one rule: once opened, it goes in the fridge.

A few things end up cooler than they need to be, but nothing goes in the wrong direction. The fridge door fills up faster, but the "hidden at the back of the shelf" accidents are mostly gone.

If I can see it, I use it. If it's hidden, I forget. Most of seasoning management, it turns out, is just that.

What stuck #3 — Write it down before it runs out

Frequent staples — soy sauce, miso — need restocking before they run out. Remembering this in the moment doesn't work either.

The rule I follow: when a bottle drops below about 30 percent, it goes on the shopping list. Writing it after it's empty means dinner doesn't happen that night.

Lately I've been using STOQ, an inventory app built for households. It works fine for one person. I've registered the seasonings I actually use, with a minimum stock level, so a near-empty soy sauce lands on my shopping list automatically.

A paper note works the same. The rule matters more than the tool. Rarely-used seasonings, I deliberately don't track. I'd rather buy them when I need them than keep an inventory that goes stale.

What three months told me

The number of bottles I throw out has dropped to one or two every six months.

It used to be five or six every three months. About a fifth of what it was. Not dramatic, but the moment of opening the cabinet and thinking "how old is this oil?" has nearly disappeared.

The heaviest part of seasoning management, I've realized, isn't throwing things away. It's the deciding. Sniff, check the label, sniff again, throw it out anyway. That small loop drains a surprising amount of energy.

Reducing the number of those decisions is the actual goal. Not zero waste. Not a perfectly tracked label.

One thing for tonight

Open one shelf. Take one photo. Don't tidy first.

Next month, take the same photo. The bottles that haven't moved will show themselves. Move them, and six months from now, your cabinet will be a little quieter than it is today.
