Preview: Homemade Mayonnaise

I like to make big batches of mayonnaise in my food processor, and unlike every recipe I've seen which says you can only keep it a week, mine keeps for two months or more in the fridge. The secret? Add several tablespoons of active-culture whey while making it, then, after putting it into your storage container, leave the container out on the counter overnight, refrigerating it in the morning. This turns your mayonnaise from a potential petri dish for bad microorganisms into a filled ecology for good organisms. Since the ecological niche is already filled, bad organisms have a hard time getting in. This makes it not only more convenient, it is a very healthy addition. One thing, though...if you use this to make Waldorf salad, you'll notice the salad tastes slightly fermented on the second day, even if you keep it in the fridge. (Personally, I think that's a plus.)

You get active-culture whey by straining active-culture yogurt through cheese-cloth or other cloth. For mayonnaise, you'll only need several tablespoons, but whey is a great addition to other culturing projects like sauerkraut or kim-chee. It ensures that it works to perfection every time.

Another trick I use for mayonnaise is to use 4/5 olive oil and 1/5 coconut oil. The two flavors balance themselves so that neither is overpowering.

When you say active culture, are you referring to yeast? How much to you put in it? Thanks.

Well, yes and no. If you're using yoghurt to get your whey (second paragraph above), then it's Lactobacilli acidophilus, a beneficial bacteria. If you're using kefir, which is what I currently use, it would be a combination of several yeasts and bacteria.

As for how much...no need to be exact. I'd use a tablespoon of whey for a small recipe, maybe three tablespoons for a large one. All you're doing is innoculating it...that is, giving it a big batch of microorganisms to get it started.

You probably can't find active-culture yogurt at a regular grocery store, unless perhaps you live in California. Look for plain, unflavored yogurt at the health-food store. It should have some variation of the words "active culture" on it. To strain out the whey, I use a very clean men's cotton handkerchief to line a large seive, and then just pour in some yogurt and let it drain into a bowl for several hours. It should produce a thin, yellow liquid that is slightly sour...that's whey.

I buy Trader Joe's French Village Nonfat yogurt. When the container is half empty and sits for a week or so a yellow liquid forms on top as it seems to be separating, kind of like natural peanut butter when the solids go to the bottom and the oil rises to the top. Is this liquid the whey, i wonder? I assure you its not bad or old yogurt, as this seems to happen to every container of that brand that i've bought, and before the expiration date and without changing taste of the yogurt.

That is whey; but, I would use a non flavored variety.
Also, at least in upstate NY, there is no problem finding active culture yogurt in any of the super markets.
Actually it seems as common as not.
I've never heard of using it as the original poster stated. It's an interesting idea...
One that I'd like to hear more about.

re: the recipe. Do you really need the mustard? The egg yolk itself is a fine emulsification agent I thought.

Culturing - another word is fermentation, also pickling - milk, vegetables, even meats, using beneficial bacteria or yeasts, is a very, very old art. Almost every traditional culture around the world cultures something. (Sorry for using two definitions of "culture" in the same sentance...) Pickles, sauerkraut, kim-chee, natto, miso, tempeh, yogurt, kefir, koumiss, kvass, kombucha, chutney...the list is endless. The only reason we don't know about it today is because our food chain has become big business, and culturing is inherantly small-batch. As a result, they replace fermentation over time with salt and vinegar, and call it "pickles" or "sauerkraut".

From the Wikipedia article on fermentation of food:

Food fermentation has been said to serve five main purposes:
1. Enrichment of the diet through development of a diversity of flavors, aromas, and textures in food substrates.
2. Preservation of substantial amounts of food through lactic acid, alcohol, acetic acid and alkaline fermentations.
3. Biological enrichment of food substrates with protein, essential amino acids, essential fatty acids, and vitamins.
4. Detoxification during food-fermentation processing.
5. A decrease in cooking times and fuel requirements.

Anyhoo, you can find lots and lots of info on the web about culturing. My favorite book is "Nourishing Traditions" by Sally Fallon and Mary Enig. It is a wonderful health treatise/cookbook, and has a great chapter on culturing.

I start with mustard , a whole egg, salt and a bit pepper
in the foodprocessor. Slowly put the (sunflower) oil in.Finally some good vinegar or lemonjuice
If it curdles add some warm water. (Even so if the mayo is too thick) One can also add garlic and/or green herbs,
or red chili.Tine

I always thought that eating raw eggs is dangerous because of salmonella.

The risk of contracting a food-borne illness or salmonella from raw eggs is quite low. However, if you are concerned about this risk, a safer alternative is to purchase pasteurized eggs.

Other things to keep in mind with mayonnaise: keep it cold at all times, try to only make the amount that you will immediately use, and store any leftovers for no more than a day or two in the refrigerator.

Can I use olive oil instead of vegetable oil? Does it matter?

You can use olive oil but just know that the flavor will be different as the olive oil itself has a stronger flavor than a vegetable oil or grapeseed oil which are more neutral. If you like you can do a mix of half olive oil and half vegetable. Cheers!

Where pasteurized eggs are sold? Is it in a container as milk or cream?

Thank you

You'll have to check in the area in which you live. Here in Vancouver, there is a company that sells them (see this thread). In the US, this company sells pasteurized eggs. Cheers!

I just whipped this up just now. It took almost no time at all, and I didn't even measure anything. I did use olive oil instead of vegetable oil. Can't tell you how much I have struggled with mayonnaise. I tried it because I saw it on a tv cooking show. The host gave so many directions that I thought it had to be really difficult. I used to be afraid to whip the oil in too fast so my arm would get tired before I got anywhere, I thought you had to add the lemon juice in two stages. I've done it in the food processor too and had troubles with broken mayo, mayo that never formed an emulsion and once the mayo got ALL over me, my glasses, my hair, the kitchen. Don't ask how that happened. It was a mess. Actually, it seems like egg yolk and mustard just want to become mayonnaise. It's crazy - crazy simple. Thanks.

Low risk? Tell it to this woman

I'd stay away from raw eggs recipes

Eggs can be an issue due to many factors: how the chickens are raised, how the eggs are packaged and shipped, how they are stored (at room temperature in Europe), the fact that in many homes eggs are stored for weeks and well past their expiration date.

In fact, eggs are one of the top 10 most allergic foods. If uncomfortable, avoid raw eggs, plain and simple. There are a lot more foods to put on the table than eggs, and if they are an issue where you live, like with processed meats and ground beef, simply use your eggs in preparations where they are fully cooked. Cheers!

Any recipes or tips for making eggless mayo? It's dreadfully expensive to buy, and for those folks who are concerned about salmonella... (we raised our own hens so I wasn't concerned), the quality of store eggs is generally very poor . I did develop an egg sensitivity so I was wondering if there was a trick to making it with grapeseed oil or other oils, and without eggs. Thanks!

Here is a site with a few recipes you can try. Let us know how it goes. Cheers!
