Recipe(tried): La Comida Tostada Sauce (copycat recipe)

The true La Comida pink sauce recipe was a mayonnaise-based sauce. Though the other mentioned recipe sounds inviting, I think it is a far stray from the original La Comida sauce. I use:

1 Cup each mayo and sour cream
La Victoria Mild or Hot Taco Sauce, to taste, and to make it pink and thin it down a bit
Splash of vinegar or lime juice
Pinch of sugar, or to taste [you don't want it sweet]

That right there is pretty close to their sauce

My variation includes the above ingredients but I often add a few Tablespoons ketchup, and a very generous squirt of Sriracha.

My family and I all grew up on La Comida in Medford and they say it tastes very close, though I am quite sure they never used Sriracha! This is a sauce you just have to play around with to your liking and you can make it mild or you can make it spicy. Use whatever brands you like. I am very confident the original was some sort of combination of mayonnaise and taco/hot sauce.

Hope this helps and enjoy
