I've had tamarind candy, tamarind soda, and even tamarind-flavored vodka. In each case, I thought it was kinda gross. Sonia grew up with such treats...well, okay, not the vodka, but the tamarind candy and beverages are something she's totally accustomed to. I think it's a Mexican thing.
To me, this sauce isn't a far cry from steak sauce, flavor-wise, but perhaps a bit more versatile. It's a bit thinner than A1 and other leading brands and perhaps a tad sweeter, but both types of sauces are tart, tangy, citrusy, and have an interesting blend of peppery spices underneath it all. This tamarind sauce is almost like a slightly fruitier version of Worcestershire sauce.
I don't think the average American wants A1-flavored candy or steak sauce soda, do you? But in its proper context as a condiment for meat, it's perfectly tasty. I'd say the same for tamarind, personally.
This sauce worked well with salmon, providing the same sort of sweet-tart element you might get from teriyaki sauce. It also went great with grilled chicken. I'm sure it would work well with white fish or shrimp. I don't eat steak very often, but I'd absolutely use it in place of A1 or Worcestershire.
It pours a deep, dark brown—almost like used motor oil. But because it's so relatively thin, it doesn't coat very well, and you can go through a lot of it quite quickly. I think it was $2.99 for about 7 oz.
We're both down for another purchase. Four stars from me. Four and a half from Sonia.
Bottom line: 8.5 out of 10.
