MiniMunch Baby Food Jars

Yes, and honestly it's the reason they exist. A jar sits straight into the steam basket, so a portion you froze last Sunday goes back into the machine without you tipping it into anything else. Lid off first, one jar at a time. Works with the basket that came in your box and with the stainless steel one, so there's nothing extra to buy.

That's the pairing they were made for. A frozen PureePops cube drops straight into a jar, so you can batch cook on Sunday, freeze the lot in the PureePops Tray, then move a portion across whenever it's needed. Lid off, jar into the KiddoKook Pro, defrosted and ready. Nothing gets scraped from one container into another along the way.

A set of four covers about two days if your baby's eating three times a day, which sounds like plenty until you're standing at the fridge on Wednesday. Most parents batch cook on a Sunday and keep the PureePops Tray in the freezer with jars holding whatever's coming up next, moving portions across as the week goes. If you'd rather have the whole week lined up and not think about it again, two sets.

Purées, absolutely. That's exactly what they're for. If you're freezing something more liquid, like water or expressed breast milk, fill to the 100ml mark and leave the space above it. Liquid expands as it freezes and glass doesn't, so give it somewhere to go. Nobody wants to lose a jar of expressed milk.

Properly, yes. Turn a filled jar upside down and nothing comes out. The silicone lid presses down over the rim to form an airtight seal, which keeps purée fresh and stops smells travelling around the fridge. Worth knowing that the lid presses on rather than clipping down, so jars are best kept upright and settled rather than loose in a bag.

In the fridge, homemade purée keeps for up to two days. In the freezer, Raising Children Network recommends no more than 30 days, so label as you go and work through the oldest first. The silicone lid takes a chalk pen beautifully, so write what's in it and the date you made it. A warm damp cloth takes it straight off when you're ready to write the next one.

Yes, jars and lids both. The glass is smooth and the lids are soft silicone, so nothing catches and nothing holds onto smells. If you've had a container keep the ghost of a bolognese for a fortnight, you'll notice the difference.

Plenty of parents start with whatever's already in the cupboard, and that works for a while. What changes is portioning. Old containers are usually the wrong size, so you either overfill and waste it or underfill and reheat twice. These hold 150ml with markings up the side, so you fill once and serve once.
