Tired of finding mould growing on your favourite jar of pesto just days after opening it? A brilliantly simple storage solution is revolutionising how Brits keep their sauces fresh, and it requires just one common kitchen ingredient.
The secret lies in a protective barrier that prevents air from reaching the pesto, significantly extending its shelf life and preserving its vibrant flavour.
The Foolproof Method For Longer-Lasting Pesto
Before you even put the lid back on your pesto jar, there's a crucial step most people miss. After each use, simply pour a thin layer of extra virgin olive oil directly onto the surface of the remaining pesto.
This clever technique creates an airtight seal that prevents oxidation and stops mould spores from contaminating your sauce. The oil acts as a natural preservative, keeping your pesto looking green and tasting fresh for weeks longer than usual.
Why This Kitchen Hack Works So Effectively
Pesto spoils quickly because its ingredients – particularly fresh basil, garlic, and pine nuts – are highly susceptible to oxidation when exposed to air. The olive oil layer effectively eliminates this exposure, dramatically slowing down the degradation process.
Food experts confirm that this method can extend pesto's freshness by up to three weeks when stored properly in the refrigerator. Not only does this save money by reducing food waste, but it also means you always have flavourful pesto ready for your pasta dishes, sandwiches, or as a flavourful marinade.
Additional Pro Tips For Maximum Freshness
- Always use clean utensils when scooping pesto to avoid introducing bacteria
- Store your pesto in the coldest part of the refrigerator, not in the door where temperature fluctuates
- Ensure the olive oil layer completely covers the pesto surface after each use
- Consider dividing large jars into smaller portions if you don't use pesto frequently
