Best USA substitute for the Spanish cheese "Queso blando de Burgos"?

[blue room]

It's described as fresh, soft, white, watery texture, slightly sweet.

I want to use it for a very simple cheese tart containing only eggs, sugar, cornstarch, cheese --
so the cheese has to be right.
Any ideas?
Maybe even something I could let drip drip drip for a day or two to make it myself?

I might use a very mild feta or even a creme cheese for the recipe you describe. You could use a ricotta too. But, as always, the final decision is yours.
