Some foods cannot be stacked, tilted or slid, and they are exactly the ones people are asked to bring to a gathering.

Why Eggs Are the Hard Case

A prepared egg half is unstable, top-heavy and filled with something soft that will not stay put.

Put two dozen in a flat container and they slide into a corner on the first turn. There is no packing arrangement that solves it, which is why a dedicated carrier exists.

Individual recesses hold each one upright, and layers mean two dozen occupy the footprint of one.

The Same Problem, Other Foods

• Cupcakes and anything iced, which smear against a lid
• Canapés and anything assembled
• Fragile biscuits, which break under their own stack
• Anything with a topping that will not survive contact
• And, outside the kitchen, craft supplies and small parts

Layered carriers that latch together and travel as one, of the kind in the Snap ‘N Stack range at mysnapware.com, are built around this rather than being general containers.

The Food Safety Part

Worth being direct about, because deviled eggs are among the more frequently implicated foods at gatherings.

Prepared eggs contain cooked egg and usually mayonnaise, both of which need refrigeration. They should be kept cold until serving and should not sit at room temperature for more than about two hours, or one in warm weather.

Transport them cold, in a cool bag with an ice pack, and put them out shortly before people eat rather than at the start.

Raw Egg

Recipes using raw or lightly cooked egg carry a salmonella risk that varies by country and by egg source.

Pregnant women, young children, older people and anyone immunocompromised are generally advised to avoid raw egg or to use pasteurised eggs. National food safety agencies publish current guidance.

Assemble on Arrival Where You Can

The professional approach. Filling piped on site rather than in advance travels considerably better and reduces the time at temperature.

Whites in one layer, filling in a piped bag in a cool bag, assembled in five minutes.

Chill Before Packing

Warm food in a sealed container condenses, which softens everything and encourages growth.

Do Not Take Leftovers Home

Anything that has been out for the length of a party should be discarded.

Wash the Carrier Properly

Recessed trays hold residue in the corners, and a brush reaches what a cloth does not.
