Technique
For sticks: cut 4mm batons, cover with 3% brine + 1 sliced ginger + 1 smashed garlic + 1 tsp mustard seed per pint. 7-10 days. For mixed ferments: grate or julienne, add at ~10% by weight of primary vegetable.
3.00% by weight is the default for carrot (workable range 2.50%–3.50%). For 1000g carrot, that's 30.0g salt. Use non-iodised salt and weigh in grams — teaspoon equivalences vary by salt grain. Source: Cultures for Health — lacto carrots.
