Eva can't say anything but eat the food happily and compliment Jake's talent, because those two dishes were once on the restaurant menu and it was Anna herself who cooked, so the restaurant had no problems with the recipe.
Also, after working so long at the restaurant Eva learned that anyone who prepared the dish with the same recipe made all the difference, she couldn't even cook all those years better than Anna or even some cooks at her restaurant.
So she could only admire Jake who was talented in everything he did, she was proud to have a child so that even though she had achieved so much at such a young age she was still humble and striving to get even better.
As Jake had come by surprise few people knew he was in Miami, Eva decided to just say that to Anna at the restaurant, Jake also didn't tell almost anyone he was in Miami, only Emily knew he was home.
