5 Secrets to Cook Ong Du ST25 Rice to Perfection: Tender, Fragrant & Wholesome

Steaming, fragrant ST25 rice forms the soulful heart of family gatherings.

“The golden water ratio, washing methods, and resting techniques that preserve the rich natural sweetness and supple texture of organic ST25 grains.”

1. Understanding ST25 Grain Characteristics

Ong Du ST25 grains are slender, translucent, and chalk-free. Their standout characteristic is an optimal amylose content (~17–18%), offering gentle bounce and tenderness without sticky clumpiness.

Processed with modern cool-air drying, the delicate bran layer retains precious B vitamins and micronutrients, calling for tender care during preparation to protect these nutrients.

2. The Five Precision Steps for Perfect Rice

Step 1: Gentle rinse: Rinse gently 1–2 times with cold water to wash away residual dust; never scrub abrasively.

Step 2: Golden 1:1 water ratio: ST25 absorbs less water than aged grains. Measure strictly 1 bowl of rice to 1.0–1.05 bowls of water (or 1.1 for softer preference).

Step 3: Uninterrupted cooking: Let the rice cooker cook undisturbed without lifting the lid to sustain internal steam vapor.

Step 4: 15-minute steam rest: When switching to Warm mode, leave the lid closed for 10–15 minutes to allow internal core gelatinization.

Step 5: Fluff with wooden chopsticks: Fluff gently from bottom to top; the grains will glisten, remain whole, and release enchanting pandan aromas.

3. Chef's Tips for Keeping Rice Soft All Day

For added luster and depth, add 2 drops of extra virgin olive oil and a tiny pinch of Himalayan pink salt before starting the cooker.

Cooled leftover ST25 makes extraordinary sushi rolls or seafood fried rice, as chilled grains retain their elastic chew without becoming hard or brittle.
