I have tried making homemade mayo 4 times and I've had enough... so please do not say it's easy. I have done it in the vitamix, with a whisk, and twice with an immersion blender I paid $60 for just because the first two methods did not work.
Is there a certain brand that is acceptable? I always used Vegannaise but figured there might be a better one out there.
Drizzling the oil in is the key. I watched my grandma make it about a billion times growing up. She just used a handheld mixture-she always told me that the only way to make it right is to DRIZZLE the oil in. If you pour it, you'll F it up.
What specific problems are you having making the mayo? As mentioned in other answers, store bought is made to travel from a production facility, sit on a store shelf, and sit in your pantry. Think about all the extra "stuff" that is needed to preserve something for that long.
Well, I use The Ojai Cook Mayo, LOVE it. Best tasting one on the market. I get it at Whole Foods. I have failed too many times trying to make mayo at home. I do not eat it very often, but when I do I get this brand. They also make Lemonaise. Perhaps it is not the healthiest compared to homemade, but at least it is the best tasting and has better ingredients than most.
In case you mess up your mayo again, you can rescue it by just putting a fresh egg yolk in a bowl and whisking the separated "soup" into it. It worked like a charm for me. the trick there is to dribble in the failed mayo slowly, re-creating the emulsion. It's a good workout for your arms. And NO wasted oil.
i tried Spectrum brand mayo before, and it tasted better than Hellmans. all of their varieties will contain some canola or soybean oil, but there is one variety that includes olive oil and another that includes flax oil.
In a punch, Veganaise makes an expeller pressed grapeseed one but it contains a small amount of soy as an egg replacement. Wilderness family naturals makes a great mayo based on Mary Enig's 3 oil blend (sesame, coconut, olive
Oil) but its a bit spendy. I would buy it in bulk. If you live in Europe, which I'm not gathering, there is an organic brand that uses an olive and sunflower blend but that's all I know of.
You definitely cannot dump all of the ingredients in a bowl or cup and produce light, fluffy goodness. An immersion blender will work great, but you still must add the oil in as thin a stream as possible. It should take about 3 minutes to incorporate a cup of oil.
My problem with making mayonnaise is that the Vitamix requires that I make a decent amount in order for it to blend properly. I found that I had too much and had to throw a lot of it away because it spoils within a few days, which bummed me out. Yes, it is great to have fresh food whenever possible, but I don't find homemade mayonnaise worth the trouble making whenever I would like to have a little of it. I am willing to use store-bought mayo for the occasional times I eat it. I've also had a tough time finding a brand that does not use canola or soybean oil. I hope Wilderness Family Naturals brings it back in stock.
