Salt Block for Cooking Food: Shrimp Tacos Method
Last updated October 25, 2026
A salt block for cooking food makes fast, evenly seasoned shrimp tacos. Heat a 12 x 8 x 1.5-inch Himalayan salt block slowly over 30 to 45 minutes, sear peeled shrimp for about 1 to 2 minutes per side, then pile them into warm tortillas with lime, cabbage, and crema.
The block does the salting for you, so skip salt in the marinade. That is the one rule that makes a salt block for cooking food different from a pan. Here's the full method, the heat schedule, a price table, and the mistakes that crack blocks.
Key Takeaways
- Heat the salt block in stages (low, medium, then high) over about 30 to 45 minutes. Rushing it is the top cause of cracks.
- Shrimp cook in about 1 to 2 minutes per side on a hot block. Pull them when the flesh turns pearly and opaque.
- Don't add salt to the shrimp. A light coat of oil is enough, and the block seasons the surface.
- One 12 x 8 inch plate holds about 15 to 20 large shrimp at a time, enough for 5 or 6 tacos per batch (our estimate).
- Let the block cool fully before you wipe it. No soap and no dishwasher.
What Is a Salt Block for Cooking Food?
A salt block for cooking food is a thick slab of rock salt that you heat on a stove or grill and cook on like a pan. The Natural Salt Co. cooking plate measures 12 x 8 x 1.5 inches and weighs about 10 lbs, cut from 98%+ pure pink salt.
Salt holds heat well and lets it go slowly, which is why a salt block for cooking food suits fast searing. The surface stays hot even after cold shrimp hit it. Food picks up a light, even saltiness where it touches the block. Wet, cold, or thick foods pick up more salt. Thin, quick-cooking foods like shrimp pick up just enough.
The 1.5-inch thickness matters. Thinner plates heat faster but crack more easily. If you're weighing a block against a thinner slab, our page on the difference between a salt block and slab lays out the trade-offs.
How Do You Make Salt Block Shrimp Tacos?
To make salt block shrimp tacos, heat the block slowly, sear oiled shrimp for 1 to 2 minutes per side, and serve them in warm tortillas. The whole cook takes under 10 minutes once the block is hot. Plan most of your time for the heat-up.
Ingredients for 8 tacos (serves 4):
- 1 lb large shrimp (21 to 25 per lb), peeled and deveined
- 1 tbsp neutral oil, 1 tsp chili powder, 1/2 tsp cumin, 1 clove garlic (grated)
- 8 small corn or flour tortillas
- Shredded cabbage, sliced radish, cilantro, lime wedges, and crema
Method:
- Place the cold salt block on a gas burner or grill grate. Set the heat to low for 15 minutes.
- Raise the heat to medium for 15 minutes, then to medium-high for 10-15 minutes.
- While the block heats, toss the shrimp with oil, chili powder, cumin, and garlic. Add no salt.
- Test the block. A drop of water should sizzle and vanish in a second or two. An infrared thermometer should read roughly 400 to 450 F.
- Lay the shrimp flat in a single layer. Cook 1 to 2 minutes, flip with tongs, then cook 1 minute more.
- Warm the tortillas on the edge of the block for about 10 seconds a side.
- Fill each tortilla with 3 shrimp, cabbage, radish, cilantro, and a squeeze of lime. Finish with crema.
Shrimp are done when the flesh is pearly and opaque. That's the doneness cue FoodSafety.gov gives for shellfish. Pull them a little early rather than late, since the block keeps cooking.
Tip: Pat the shrimp dry with paper towels before oiling. Surface water steams, pulls more salt, and stops a good sear.
How Long Does It Take to Heat a Himalayan Salt Block?
A Himalayan salt block takes about 30 to 45 minutes to heat for searing. Raise the heat in stages so the inside and outside warm at a similar rate. A block that goes from cold to high flame in five minutes can crack or pop as trapped moisture expands.
When we test new plates in Cockeysville, the first heat always goes slowest. The product page tells you to heat gradually from low to high for the first few uses to cure the block. Light cracks and a slight color change after the first few heats are normal. Deep cracks that run through the plate are not.
Any Himalayan salt cooking plate works on gas burners and grills. Electric stovetops are listed too, but check your stove maker's guidance first, since some glass tops have weight and heat limits. For more on sizing, see this salt cooking plate size guide.

Common Mistakes With Salt Block Cooking
- Heating too fast. Go low, medium, then high. Patience saves the block.
- Salting the marinade. The block adds salt. Extra salt makes the shrimp taste harsh.
- Crowding the surface. Too many cold shrimp drop the temperature, and they steam. Cook in batches.
- Using wet marinades. Liquid pools, pulls salt, and can pit the surface. Keep it to oil and dry spices.
- Wash it hot. Water on a hot block can crack it. Let it cool for several hours, then wipe with a damp cloth and scrape.
Treat a salt block for cooking food like cast iron that hates rushing. We hear the same story from first-time cooks: the block cracked on night one because the burner went straight to high. Give it the full heat-up and a salt block lasts for many meals. Moving a hot 10 lb block is risky, so leave it in place to cool.
Frequently Asked Questions
Do shrimp get too salty on a salt block?
Not when the block is hot and the shrimp are dry. Fast contact gives them a light seasoning. Shrimp get too salty when the block is underheated, the shrimp are wet, or they sit too long. Skip salt in the marinade and taste the first batch before adjusting.
Can I use a salt block on a gas grill?
Yes. Set the block on the grate over the burners and heat it in stages with the lid closed for the last 10 to 15 minutes. A gas grill heats more evenly than charcoal. Keep the block away from direct flare-ups while it warms.
How do I clean a salt block after cooking shrimp?
Let it cool completely, then wipe it with a lightly damp cloth or sponge. Scrape stuck bits with a spatula. Use no soap and no dishwasher. Dry it fully and store it somewhere dry. A thin layer of salt dissolves each time, which keeps the surface fresh.
What else can I cook on a salt block besides shrimp?
Thin, fast-cooking foods do best: scallops, sliced steak, fish fillets, asparagus, and thin-sliced vegetables. A chilled block also works for serving sushi, cheese, or fruit. Thick cuts that need long cooking times tend to pick up too much salt on the surface.
Final Word on Using a Salt Block for Cooking Food
A salt block for cooking food turns shrimp tacos into a quick, hands-on meal. Heat the block in stages, keep the shrimp dry and unsalted, and cook in small batches. Then fill your tortillas and let the block cool where it sits.
