Frequently asked questions
How many peas should you allow for per person at a barbecue?
A small tin may be enough if the peas are just a side, but compare the drained net weight and number of portions rather than the tin’s weight alone. Carrefour’s range includes 140 g tins; also check whether they’re sold individually or in a multipack.
Can you serve tinned peas cold?
Yes, if the product instructions say you can. For a Jardin Bio Etic product, Carrefour says it can be eaten cold in a salad or served hot as a side. Check the instructions on your own tin for preparation and serving advice.
How should you store peas after opening?
Follow the instructions for the product you’ve opened and put any leftovers in the fridge promptly. For the “tender and creamy” product it lists, Bonduelle says to keep it at a maximum of 4 °C and eat it within 48 hours of opening. Don’t automatically apply these instructions to another tin.
What should you do if a tin looks swollen or damaged?
If you think the packaging may be compromised, don’t taste the contents. Set the product aside and ask the retailer or manufacturer for advice. France’s Ministry of Agriculture warns that certain toxins linked to botulism pose a serious danger, so it’s not worth taking a risk with a suspect tin.
How should you recycle an empty tin in France?
Put the empty metal tin in the recycling bin, bag or container for packaging. According to ADEME, there’s no need to wash it; put it in loose, without nesting it inside another piece of packaging.
