Since there is avocado in this spread, it will brown over time. However, there are a couple of ingredients in the spread that should help reduce the natural browning process including the use of lemon juice, extra virgin olive oil and red onion. To further help, press a layer of cling wrap on top of the spread, then seal with an airtight lid before refrigerating. Doing this will reduce the amount of oxygen hitting the avocado and allow the spread to last 3-4 days.
