Re: pretty basic
Hummmm...
I understand that every Dominican household has a different variation to making this dish, but Dominicans as a whole make it much different than the recipe you have.
The following is how we used make ensalada de bacalao for ages.
Depending on how much salad you are going to make, 5 - 10 of the following vegetables should do. Basically, the vegetables for boiling (in salted water) are potatoes, carrots, and tayotas. Yautia is optional. Most Dominican homes don't use yautia when preparing this dish. Boiled yautia is just too bland and not as tender as the other veggies. What IS added is hard-boiled eggs (2-3) instead.
You should soak the bacalao in cold water over night if you can, or for a couple of hours at least. 1/2 - 1lb. of bacalao should do. You are going to boil it in order to tenderdize it and de-salt (or is it un-salted?) it as much as possible. After boiling it, the bacalao should be very tender and flaky. You should be able to easily "shread" it with your hands. You don't cube it.
After the veggies and eggs are boiled, you are going to slice them, or cut them into "tajadas" or "ruedas", sort of following their natural shape. Again, I have never heard of cubing them.
We usually assemble the veggies on an oval dish. The bed for the salad becomes your boiled veggies. On top you assemble the bacalao and finish topping with the hard-boiled eggs.
As for dressing, you use the typical Dominican vinagrette - extra virgin olive oil, vinegar and salt. For this salad though, you want to use more olive oil than vinegar, and you should not need that much salt either because you have boiled the veggies in salted water already. We never used recaito. What is commonly used is slices of raw onions instead. I personally skip them.
Enjoy!
