How We Research

Updated on

Every guide on Plum Melo answers one question: will this cooker or container work well for the way you cook? That means the right power, the right size and controls you'll be glad to use.

Here is how we get to an answer.

1. We start with how you cook

Someone cooking two steaks on a weeknight needs something different from someone cooking a brisket for a crowd. We start each guide with the cook, the batch size and the space in your kitchen.

When a model only suits certain cooks, we say so.

2. We compare power and control

We look at wattage, the temperature range, how the cooker shows the set point and whether it runs from buttons, an app or both. We also note the timer, the clip or clamp and the minimum and maximum water lines.

Makers describe their own products, so we name the brand for every claim. For example, we write "Anova says" rather than stating a promise as fact.

3. We check size and build

We note the height, weight and width of each cooker, and how much water it's rated to heat. For containers, we check the quarts, the lid style, any rack and whether the lid has a cutout for the cooker.

4. We read what owners report

We look for patterns in what owners say after months of use. Pump noise, app trouble, clips that slip, lids that warp and units that stop heating all count.

One unhappy owner doesn't sink a model. A pattern does.

5. We score each product

Our score weighs specs, features and owner feedback against what you're shopping for. A cooker that suits one guide may score lower in a guide written for a different cook.

Scores spread out on purpose. A 10 is rare.

6. We keep pages current

Models change, and makers sell close cousins under similar names. We check model numbers, link only new units and skip any model with a known recall.

When a guide changes in a real way, the "Updated on" date at the top changes with it.

What our picks are not

Our picks come from research, not lab tests. We don't claim to have cooked with every model we cover.

For times, temperatures and safe handling, we point to USDA and FDA guidance. Sous vide uses hot water and household power, so follow the maker's manual for every cooker.
