Bake garlic: Slice the top off the garlic and place into an ovenproof dish with a lid or sheet of alfoil. Season with 1 tablespoon olive oil and a pinch of salt. Cover and bake for 1 hour or until the garlic has browned in colour. Allow the garlic to slightly cool and squeeze out the cloves.
Blend: Place all ingredients into glass container or jug that is just wide enough to fit an immersion blender. Using an immersion blender, blend all ingredients together being careful to not move the blender up and down. Once the ingredients begin to emulsify, move the blender up and down while slowly incorporating all of the oil. Continue until you have a thick consistency.
Store: Store in an airtight container or jar in the fridge for up to 2 weeks.
Notes
Oil: Olive oil is a popular choice for making mayonnaise, especially if you're looking for a richer, more flavorful and heart-healthy option. While traditional mayonnaise often uses neutral oils for a milder taste, extra virgin olive oil adds depth and a slightly peppery finish. It can be a bit bold on its own, so some people prefer to use a lighter olive oil or blend it with a neutral oil to soften the flavor. Either way, olive oil gives homemade mayonnaise a more wholesome and Mediterranean feel. Chilli & Lime: To keep this mayonnaise more classic, these ingredients can be skipped!
