How to make Curtido

Name: Curtido
Total time: 5 d
Ingredients: 800 g Green cabbage; 150 g Carrots; 100 g White onion; 20 g Sea salt; 3 g Dried oregano; 1 whole Red chilli

A tangy Salvadoran slaw of cabbage, carrot, and onion, lightly fermented with salt and oregano. Expect about 30 minutes of active prep, then 3-5 days of fermentation, with a taste check to decide when it is tart enough to refrigerate.

Quick answer

Prepare the vegetables, draw out enough brine with salt, and pack everything tightly into a clean jar. After 2 days, confirm that fermentation has started and reset the vegetables below the brine if needed. After 3 days, taste the curtido and decide whether to refrigerate it now or let it keep fermenting. After 5 days, do a final flavour check, then move the finished curtido to sealed cold storage.

Safety

• Keep every piece of vegetable below the brine line. Exposure to air is the fastest route to mold.
• A clean sour smell is normal. A rotten or putrid smell means the batch should be discarded.
• Use a clean jar and non-iodized salt so the right microbes can take hold early.

Ingredients

• 800 g Green cabbage Fresh and firm, outer leaves reserved as weights
• 150 g Carrots Peeled and coarsely grated
• 100 g White onion Halved and thinly sliced
• 20 g Sea salt Non-iodized only -- about 2% of vegetable weight
• 3 g Dried oregano Roughly 1 tbsp, Mexican oregano if you have it
• 1 whole Red chilli Optional, thinly sliced for mild heat

Equipment

1-1.5 L wide-mouth jar Large enough for the vegetables, released brine, and a little headspace.
Large mixing bowl Use it to salt and massage the vegetables before packing.
Knife, mandoline, and grater Even cuts ferment more consistently than random chunks.
Kitchen scale Needed to keep the salt close to 2 percent of the vegetable weight.
Clean weight or reserved cabbage leaf Helps keep every piece below the brine line.

Step-by-step

Day 0

Step 1: Prepare and pack

Prepare the vegetables, draw out enough brine with salt, and pack everything tightly into a clean jar.

Set up clean equipment Wash the jar, bowl, weight, and any utensils before you start.
Prepare vegetables Shred the cabbage, grate the carrot, and thinly slice the onion so everything ferments at the same pace.
Salt and massage Add all 20 g of salt and the oregano, then massage for 8-10 minutes until the vegetables soften and release brine.
Pack and submerge Pack the slaw and all of its brine into a clean jar, pressing out air pockets and keeping the solids below the liquid.

Day 2

Step 2: Check fermentation

Confirm that fermentation has started and reset the vegetables below the brine if needed.

Check submersion Press any floating vegetables back under the brine and top up with 2 percent salt water if the level has dropped.
Check activity Look for small bubbles, cloudy brine, or a faint tangy aroma as signs that fermentation is underway.
Check aroma A clean, fresh sour smell is normal and more useful than chasing an exact day count.

Day 3

Step 3: Taste and decide

Taste the curtido and decide whether to refrigerate it now or let it keep fermenting.

Taste curtido Use a clean fork to take a small bite and judge both the acidity and the crunch.
Resubmerge and cover Return the slaw below the brine before putting the jar back in its fermentation spot.

Day 5

Step 4: Finish and store

Do a final flavour check, then move the finished curtido to sealed cold storage.

Taste final batch Confirm that the curtido is tangy enough and still has the texture you want before ending warm fermentation.
Transfer and refrigerate Pack the finished curtido into clean storage jars, keep it under brine, and refrigerate to slow further fermentation.

What to look for

• Day 0: The cabbage turns glossy, softens noticeably, and leaves a pool of brine in the bowl. Those cues tell you there is enough liquid to pack the jar without dry pockets.
• Day 2: The brine looks slightly cloudy and you may see a few bubbles against the glass. Those are normal early signs that the ferment has started, even if activity is still gentle.
• Day 3 and beyond: It smells clean and sour, and a small taste is crisp with light acidity. Use that first taste to decide whether to refrigerate now or keep fermenting for more tang.

Troubleshooting

Brine does not rise above the vegetables. The cabbage was dry or it was not massaged long enough. Massage a little longer, then top up with 2 percent salt water until all solids are covered.
The curtido tastes too salty. The salt ratio ran high or the ferment is still very young. Let it ferment another day or two before judging it, then serve it with unsalted foods if needed.
The texture turns too soft. The vegetables were cut too thin or fermented too warm for too long. Stop the ferment sooner next time, cut slightly thicker, and keep the jar closer to the cooler end of the range.
Surface mold appears. Solids floated above the brine or the jar rim stayed dirty. Discard the batch and restart with better submersion and a cleaner setup.

Storage

Once it tastes tangy enough for you, transfer it to clean jars with enough brine to keep it submerged, seal tightly, and refrigerate.

Shelf life: about 1-2 months refrigerated
