Yeolmu kimchi is made from young radish plants, leaves and thin roots together, salted and mixed with green onion, red chilli, chilli powder, garlic, ginger and anchovy sauce. It is a spring and summer kimchi; a watery form, yeolmu mul-kimchi, is thickened with a little starch and sours faster. Made in 4 steps over 18 days – 25 days. The longest step, ripen cold, takes 14–21 days (Kong C.-S 2005) and runs at 5 °C (Kong C.-S 2005). Salt is 1.8–2.4 % (강근옥 1995). Leuconostoc, at its highest count when the kimchi reaches best ripeness at 5 °C and Lactobacillus, high from early on in the watery form do most of the fermenting.
Amounts from a sourceMean amounts per 100 g of salted young radish, standardized in 2005 from Korean cookbooks and literature by the Kimchi Research Institute of Pusan National University. Only ingredients used in more than half of the recipes were kept.

What makes this one different
Yeolmu kimchi uses the whole young radish plant, tender leaves and thin roots together, where kkakdugi and chonggak kimchi are built on the radish root. At best ripeness at 5 °C it carries much more acid than the watery form, 1.04–1.27 % against 0.20 %.
Yeolmu mul-kimchi (watery young radish kimchi)Per 100 mL of water, 50.6 g salted young radish with garlic, ginger, green onion, green and red chilli and 1.5 g starch. At 5 °C it reached pH 4.3 in 9 days with acidity of only 0.20 %.
Safety
A survey of Korean kimchi found lower biogenic amine levels in yeolmu kimchi than in baechu kimchi. In storage, its nitrate fell by about 12 % from the day it was made.
A 1995 survey in Seoul and Chungcheong listed yeolmu kimchi among the kimchi made in spring, when less salted seafood and more fresh vegetables were used.
