• Flowers and juice: Flowers of the palm trees can produce so much juice and the sugar from it. There are two types of juice: sweet and sour juice. Sweet juice is the fresh juice that was just taken from the flowers. If you keep for many hours, it will become sour. This sour juice is called "Teuk Thnot Ju / Sour Palm Juice". It is like a wine, just keep without brewing. There are palm juice wine you can find at the market these days. For sweet juice, you can drink it like sugar cane juice or refine it for sugar palm. Some farmers who run family sugar business can produce up to 5 tons of sugar palm per year (best time to harvest is dry and hot season between Jan to April). This can give them so much incomes and benefits, of course brown sugar is made from palm juice and very beneficial to health (one kilo of sugar palm: 5$-10$). Kompong Speu province has much palm trees in Cambodia for the record, and also produces the #1 Quality of Palm Sugar or Brown Sugar. Prey Veng (my home province) has #2 quality, then Kompong Chhnang and Kompong Cham.
