To freeze: Freeze soup, in individual portions, in airtight containers for up to 2 months.
Look for packets of peas with loose peas and avoid those that are icy with frozen clumps. This can be an indication of freezer burn or re-freezing, which can affect flavour.
Where possible add peas towards the end of cooking time to prevent them becoming too soft and losing their bright green colour.
