Super yellow butter. I didn’t know what to make of it. It was so bright I was sure some food coloring must have been added.
Come to find out this bright yellow butter that is the norm in Mexico is what it looks like when cows eat a natural diet. Natural meaning grass and flowers. It is the beta-carotene, with its yellow pigment, that gives butter it’s yellow color. Less beta-carotene, the more opaque the butter.
Not all animals operate the way cows do. That is why butter from sheep and goats is white; they don’t store the beta-carotene the same as cows.

Still, no matter where the cows are grazing, it’s hard to have them grazing year-round on grass. Because the consumer wants consistency with their purchases and not having fluctuating butter color during the year, as would be natural, those making the butter often freeze it during peak season in order to have it for sale year round.
In the United States the freezing part isn’t usually an issue because so few dairy cows ever eat a green meal. Those cows usually get a mixture of barley, corn and alfalfa in a feed lot instead of a pasture. The diet is consistent, thus producing consistently light colored butter.
Besides looking different, the butter in Mexico also tastes different. Richer would be one word to describe the difference. It also tastes a bit like the butter you get on popcorn at a movie theater, and even has that smell.
It’s like a lot of foods, they are similar, but not the same in every country. (Even Diet Coke – Coca-Cola Light here – is different; it’s sweeter in Mexico.) It’s a matter of getting used to things and being open to adapting to the world you are in and not holding on so tight to the world you came from.

While what the cows are being fed clearly makes a difference, mantequilla (butter) is not used as much in Mexican cooking as it is in the United States, other than in baked goods. Oil and cream are more popular.
If one doesn’t want to adapt, it’s possible to get U.S. butter in Baja California Sur. At Supermercado Del Sol II in Todos Santos one cube of Challenge butter (113 grams) was 40.75 pesos (more than $2). This compares to a local brand – Gloria – and its bright yellowness being 20 pesos (about $1) for 90 grams.
That’s interesting ….but if you look on the label , I believe the Mexican butter has soy added . My favorite butter in the states is Kerrygold from Ireland, expensive but there’s a difference.
Kerrygold my fav too!
Looked at label too, it has no soy.
I loved the butter in Tulum Mexico, which I could get in the states
Have you noticed the difference in the color or egg yolks – Mexican yolks are almost orange as opposed to US yolks that are yellow. And so much tastier!
Mexico eggs taste and look farm fresh. They also aren’t all uniform in size.
chickens that eat grass have darker yokes. farm eggs in the us and canada that. are outside eating grass will also have darker yokes
From reading a few of the Gloria mantequilla labels online, it does have added soy lecithin as an emuslifier, though I don’t understand why, perhaps it’s because they also add water. They add colour too, annatto. I’m not sure if ALL of their butter is like this, or if they sell one type that is more pure.
The eggs I buy from local people who raise chickens have dark orange- yellow yokes compared to the eggs I buy at the supermarket.
Gloria butter separates when it melts which has me wondering how a pure cream butter would separate.
I use Organic Valley Grass-Fed butter at home and found the butter in Mexico was not as rich or flavorful. The orange egg yolks are from chickens running loose, eating the proper diet – grass & bugs. The grass contains beta-carotene which turns the yolks orange.
