Remove a thin slice from the stem end of each tomato.
Remove seeds and some pulp, sprinkle inside with salt, and invert to let stand for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Serve as the hollow shell that holds the filling.
- Mayonnaise
- Binds the celery and walnuts and adds moisture and richness to the filling.
- Walnuts
- Add crunch and a toasty, nutty texture against the soft filling.
- Celery
- Adds crisp texture and a fresh, mild crunch to the filling.
The step that matters
Letting the salted tomatoes stand. Salt draws water out of the tomato flesh through osmosis. Standing upside down for 30 minutes lets excess juice drain, so the filling stays firm and does not make the shells soggy or watery.
Swap the walnut
How well each one fits the dish's main ingredients (tomato, celery, lettuce, shrimp):
- Beansfits better
- Chickpeafits better
- Sesamefits better
- Walnutthe original
Fit is the average pairing score against tomato, celery, lettuce, shrimp. Candidates are from the same food group and used in at least 100 recipes.
