マラキーノック / Momordica charantia L.
Mara khi nok (small/wild bitter gourd) is a small, strongly bitter form of bitter gourd called "mara khinok" in Thai folk classification. It has the same scientific name as bitter gourd, but in Thailand is treated alongside the Chinese-type mara jeen (มะระจีน) as a separate folk category of smaller, more bitter fruit.

Reading the bitterness
Mara khinok is a Thai folk term for a small, strongly bitter bitter gourd of the species Momordica charantia L. A university article for households introduces the bitter gourds commonly eaten in Thailand as 2 categories, Chinese-type mara jeen and mara khinok. A local-government source says the leaves are bitter and raw fruit has especially strong bitterness.
Before using mara khinok in other dishes, one described preparation is to boil it in vigorously boiling salted water and discard the water once cooked to reduce bitterness; another is to squeeze it in salt water. No values are given for boiling time, water quantity, or the extent of bitterness reduction.
After this pretreatment, it is described as used in spicy curries, panang, khua-style curry, northeastern Thai mushroom curry, and stir-fried eggs. The small, strongly bitter fruit is briefly boiled before appearing in various stewed and stir-fried dishes. The source does not give proportions or quantities for any of the dishes.
Mara khinok is recorded under the same scientific name as the existing bitter-gourd entry, not as a formally distinguished botanical variety. There is no direct description comparing its bitterness intensity with mara jeen. The parallel listing of local names supports only treating it as a folk category of smaller fruit described as more bitter.

Scope: A list of scientific and local names recorded in a publicly released Thai local-government source
Note: The source gives the same scientific name, Momordica charantia L. The side-by-side listing of the 2 types, including mara jeen (the Chinese-derived type), is based on a separate source (a home-cooking explanation from Suan Dusit). This is not a claim of a formal varietal name.
