Salsa is one of the most useful things to dry from a summer garden. Tomatoes, onions, peppers, cilantro and lime all dry well together, and the result rehydrates into a passable fresh-style salsa in a few minutes.
Ready-to-serve salsa is about 89% water, so a pint jar dries to just a few ounces of flakes. Crumble it for salsa, or grind it to powder and stir it into rice, beans, eggs or dips as a seasoning.
Chunky and smooth salsas both work. Chunky salsa keeps more texture but takes longer, because the thicker tomato and onion pieces hold water. Pour off thin juice from very watery salsa so it dries in a reasonable time.
Prep and loading
- Use fresh, cooked or jarred salsa. Pour off extra juice.
- Spread about ⅜ inch deep on lined trays or silicone mats.
- Pre-freeze the trays.
- After drying, crumble into flakes or grind to powder.
How to tell it’s dry
- The sheet breaks into crisp pieces with no soft or cool spots.
- Onion and pepper chunks snap.
A steady weight only shows the drying has stopped; breaking the thickest piece is the check that counts. Neither is a safety test. Safety comes from tested prep, safe cooking temperatures where needed, complete drying and airtight packing. See what a kitchen scale can and cannot tell you.
Not sure? The weight check compares two weighings and the expected dry weight for salsa.
Problems and fixes
Oily surface
Some salsas contain oil. Choose one without, or blot the top before drying, and eat those bags sooner.
Too thin after rehydrating
Add water a little at a time. It is easy to add more and hard to take it out.
Rehydrating and storing
Rehydrate: Mix with cold water a spoonful at a time, then rest 5 minutes. By weight, 100 g of dried salsa takes back about 782 g of water to return to fresh weight; the rehydration calculator does any amount.
Store: Mylar with an oxygen absorber. Powder absorbs moisture quickly; keep the jar you use small and closed.
Ways to use it
- Camp burritos and eggs
- Seasoning for rice and beans
- Dip mix with sour cream
How much fits per batch
At a normal single layer, salsa load at roughly 2.2 lb of fresh food per square foot of tray. That works out to:
| Machine | Fresh per batch | Dried per batch |
|---|---|---|
| Harvest Right Countertop 360 | 5.5 lb | 9.9 oz |
| Harvest Right Small | 6.6 lb | 12.0 oz |
| Harvest Right Medium | 10.3 lb | 1.17 lb |
| Harvest Right Large | 16.9 lb | 1.92 lb |
| Harvest Right X-Large | 34.4 lb | 3.90 lb |
