It’s long since been established that eggs aren’t a necessary ingredient for a successful mayonnaise. Save recipes with a large quantity of egg yolks, their inclusion has never been for flavour but rather for their emulsifying and stabilising properties. Emulsification is when two liquids are combined in a way so that one is suspended in the other, such as the suspension of oil in water as is the case in mayonnaise.
Anyone who’s paid the slightest bit of attention to life has probably noticed that oil and water don’t mix, or not without a little help anyway. Emulsifiers are utilised as that helping hand, the force to make these opposites stop being so, um, oppositional and hang out together already. Because a mayonnaise free life would be pretty miserable.
Okay, so will homemade mayonnaise attempts fail if you take egg yolks or an equivalent emulsifier out of the equation? Well, not really. Despite everyone talking about emulsifying stuff to make stuff that’s stable stuff, it’s still possible to force a semi stable emulsion even in the absence of an emulsifier.
Clear as mud, yes?
Making a semi stable mayonnaise
The reference to semi stability infers that the egg free mayonnaise will not maintain its stable form forever, and that is true if an emulsifying agent isn’t added. The addition of egg yolks keeps mayonnaise stable over a longer period, but unless you plan on waiting until your mayo has a fuzzy layer of added growth then you don’t need to worry too much. The vegan mayonnaise recipe I’ve provided is stable enough to last for awhile, and even if it loses some of it’s whippiness then just give it a whiz in the Vitamix (how did I get to be so middle class?) or with a hand held immersion blender to perk it back up.
Each emulsifier molecule contains two polar ends, one that’s hydrophobic and one that’s hydrophilic. The former end loves water and will happily bond with it, but the hydrophilic end isn’t a player and wants nothing to do with water. The oil-loving end gets dug into the oil while the water-loving end gets cosy with the water, and then the whole lot is stuck together and hence stabily emulsified.
So basically, this vegan mayonnaise recipe isn’t emulsified in a way that meets the true definition of emulsification (as it’s missing an emulsifier), but it still works because yay science. I could explain further, but for the time being I’m going to assume you’re fed up with reading and you just want to make some mayonnaise already. OMG just be quiet and tell me how to do this thing. Okay.
Further recipe notes
I made this in my Vitamix, so the instructions refer to the settings for a high powered blender only. It’s possible to make vegan mayonnaise with hand held blenders and other liquidisers, and I wager you will have success in trying to do so.
Keep in mind the temperature of the blender’s contents as you go. Let it overheat and you will end up with an oily mass that will not solidify. That said, it’s best to start with room temperature ingredients (a little warmth in the oil can even be beneficial). Just know that extreme temperatures will affect the consistency.
Homemade Garlic Lime Vegan Mayonnaise
- Liquidise all of the ingredients but the oil, until the garlic is broken down completely and the liquid is thoroughly blended (10-15 seconds on a medium-low to medium setting should do the trick).
- While the machine is running on a medium setting, slowly drizzle the oil into the blender. The contents will begin to thicken after half to ¾ of the oil has been added, and will be the right consistency by the time the last drop falls in.
- Refrigerate and use as desired within a week or two.
