To make the soaked drink, place a tablespoon (around 10 g) of whole flaxseeds into a glass or jar and add at least 200 ml of cool or room‑temperature water. Stir briefly, then let the mixture stand for at least 20–30 minutes, or cover and leave in the refrigerator for several hours or overnight.
During soaking, the soluble fiber in the seeds absorbs water and swells, creating a noticeable gel‑like layer around each seed and thickening the liquid. You can drink the mixture as is (the seeds will sink to the bottom), strain it if you prefer just the gel, or pour the entire content into a smoothie for extra body.
Because the gel forms through hydration, it's advisable to drink an additional glass of water afterward. If you are introducing flaxseed to your diet, start with a smaller amount (e.g., a teaspoon) to see how your digestion responds.
