Fermented milk from Nabadwip, Nadia district, West Bengal
Nabadwip lal doi (red curd of Nabadwip)নবদ্বীপের লাল দই
Milk is boiled down on a wood fire until about three litres become one and the milk reddens, with no colour added. It is poured into clay pots set around the fuel, covered, and left to set into a curd firm enough that a pot can be turned upside down. A knife (chakku) is used to test or cut it.

At a glance
Milk is boiled down on a wood fire until about three litres become one and the milk reddens, with no colour added. It is poured into clay pots set around the fuel, covered, and left to set into a curd firm enough that a pot can be turned upside down. A knife (chakku) is used to test or cut it. Made in 3 steps over 2 h – 6 h. The longest step, boil the milk down until it turns red, takes 2–6 h (Wikipedia 2012).
Lal doi is red from hours of boiling the milk down, with no colour added, and is much denser than white doi because the milk is boiled to about a third.
Lal gholThe red whey the Ghosh brothers are said to have made from the reddened milk; the source calls their whey-making area Red Ghol or Red Whey.
Safety
The milk is boiled down for two to six hours on a wood fire before it is poured into the pots to set. Wikipedia says the curd can be stored up to ten days.
The red curd is credited to Kali Ghosh of Phasitala in Nabadwip, or to Kalipada Modak, in 1930. The Ghosh brothers, Kali and Hari, mostly made curd and whey; they boiled buffalo milk gently, with a little water, for a long time, and it turned red. Their whey-making area was known as Red Ghol or Red Whey.
