Đồ chua

Vietnamese pickled carrot and daikon: the essential condiment of the Vietnamese table

Origin: Vietnam

From the journey of Carrot.

Đồ chua (literally 'sour stuff') is the fundamental condiment of Vietnamese cooking, thin matchsticks of carrot and daikon (white radish) quick-pickled in rice vinegar, sugar, and salt, then served as a bright, crunchy counterpoint to the richness of grilled meats, braised pork, and fried egg rolls. It appears on the Vietnamese table with a frequency that makes it nearly invisible, it is always there, tucked into bánh mì sandwiches (where it is one of the defining components), piled alongside bún thịt nướng (grilled pork noodles), and served as a palate-cleanser throughout a meal. The quick pickle tradition (as opposed to the long fermentation of kimchi or European sauerkraut) produces a condiment that retains crunch and freshness. The carrot contributes sweetness and vivid colour; the daikon contributes a clean, peppery bite. Together they exemplify the Vietnamese aesthetic of balance and contrast: the pickles cut through fat, cool heat, and provide textural relief. The carrot, introduced to Vietnam during the period of French colonial influence in the late 19th and early 20th centuries, was rapidly absorbed into the Vietnamese culinary vocabulary: Đồ chua is perhaps the clearest example of a new ingredient becoming so thoroughly integrated into a cuisine that it is now considered quintessentially Vietnamese.

Ingredients

Carrot

200 g carrots, peeled and julienned into thin matchsticks

Daikon

200 g daikon (white radish), peeled and julienned into thin matchsticks

Salt step

1 tsp fine salt
1 tsp sugar (for salt step)

Brine

120 ml rice vinegar (unseasoned)
120 ml warm water
3 tbsp caster sugar
0.5 tsp fine salt

Method

Julienne the carrot and daikon into matchsticks approximately 5–6cm long and 3mm thick. A mandolin with a julienne blade produces the most consistent result; a sharp knife and steady hand work equally well.
Place the julienned carrot and daikon in a bowl. Add 1 tsp each of salt and sugar. Toss together and leave for 10–15 minutes. This draws out excess moisture and slightly softens the vegetables.
Rinse the vegetables under cold water to remove the salt and sugar. Squeeze firmly but gently to remove as much moisture as possible. Pat dry with a clean cloth or paper towels.
Make the brine: combine the rice vinegar, warm water, sugar, and salt. Stir until the sugar dissolves completely.
Pack the vegetables into a clean jar or container. Pour the brine over them: it should cover the vegetables completely.
Leave to pickle at room temperature for at least 1 hour before using. The pickles will be ready to eat after 1 hour, crunchy and lightly acidic; they become more fully pickled and softer after 24 hours.

Notes

Đồ chua keeps in the refrigerator for 2–3 weeks in a sealed jar. The pickles are most crunchy in the first 2–3 days and soften progressively over time: both stages are useful for different applications. To use in bánh mì: drain the pickles and layer generously in the sandwich with pâté, sliced meat, fresh cucumber, jalapeño, and fresh coriander. The pickles provide the essential sweet-sour-crunchy counterpoint that makes bánh mì one of the world's great sandwiches.
