Homemade Mayonnaise Recipe (2024)

FAQs

Why is homemade mayo not advisable? ›

Second, unlike commercial mayonnaise that's made with pasteurized eggs, homemade versions are typically prepared with unpasteurized raw eggs, which limits their food safety and means they don't last long in the fridge.

Safflower, canola, grapeseed and peanut oil all do nicely. Just make sure the oil is at the same temperature as the egg. You can use cold oil and cold eggs, but I found room temperature eggs and oil to be the easiest to work with.

the various ingredients used to make the mayonnaise are not room temperature; the ingredients have not been dosed correctly; perhaps you have added too much oil or lemon juice; the ingredients (oil and lemon juice) were not added gradually to the mix.

The United States Department of Agriculture does not recommend eating raw shell eggs that are not cooked or undercooked due to the possibility that Salmonella bacteria may be present. However, homemade mayonnaise can be safely made if raw, in-shell pasteurized eggs or pasteurized egg products are used.

Homemade mayonnaise has a shelf life of about two weeks, because it doesn't contain any preservatives. That's a long shelf life, and you'll probably go through all of it before then! It's just that fresh and delicious.

Egg Yolks, the Emulsifier. Add egg yolks and salt; pulse to combine. Egg yolks contain lecithin, which resembles both oil and water molecules and can connect to both. The salt boosts flavor and makes eggs more viscous, which helps prevent separation.

Why Mayo Breaks: Too much oil was added at once. A lot of the time, if you add all of the oil at once, it is too much for the egg to take and it won't emulsify. Blender / immersion blender isn't strong enough for all the oil at once.

However, a more promising explanation for the bitterness is the presence of polyphenols, like oleuropein in olive oil, which are known to taste bitter and scientists consider them to be responsible for the bitterness that shows up in olive-oil based mayonnaise.

This is because mayonnaise is an emulsion that requires a specific balance of ingredients for it to work. If you don't get your measurements right, or add an ingredient too quickly, your mayo may end up runny. If this happens to you, don't throw the mixture out quite yet -- there is a simple solution: egg yolk.

That said it is also a method with little to no margin of error for the consistency; it is completely possible to overmix mayonnaise when making it at such a high speed. If that happens thin it out with water while mixing with a wire whisk.

What two ingredients make mayonnaise a permanent emulsion? ›

In the case of mayonnaise and hollandaise, it's the lecithin in the egg yolks that acts as the emulsifier. Lecithin, a fatty substance that is soluble in both fat and water, will readily combine with both the egg yolk and the oil or butter, essentially holding the two liquids together permanently.

The yolk contains the emulsifier lecithin (phospholipids), which is necessary to form the O/W emulsion in mayonnaise. It also contributes the 'eggy' flavour and yellow cast to the mayonnaise.

However, a 2012 study found homemade mayonnaise may still contain salmonella bacteria despite different acidic compounds used. 4 Because of this, some people prefer to pasteurize an egg in 140°F water for 3 minutes before making mayonnaise.

But only when it's homemade. Store-bought mayonnaise is unhealthy because all brands available to us contain unhealthy oils, sugar and other additives. And as a rule of thumb, if you want to know how bad a certain brand of mayonnaise is, just look at what oil is used to make it.

So many store-bought mayos are laden with ingredients like canola oil, added sugar, and/or preservatives. With homemade mayo, like anything else, you are in charge of exactly what you put into it, which means that you can choose to use better-for-you ingredients, instead.

Homemade mayo is ultra creamy and much more flavorful than anything you can buy at the store. This recipe calls for a simple list of ingredients and takes less than 10 minutes to make!
