ELEO Seedri kohv SLIM is designed as a hot beverage. The exact serving size and preparation method are printed on the label of the 130 g pack, so the most reliable approach is to follow that. With chicory-based drinks of this type, the usual method is to put one serving into a cup or mug, add hot water, and mix well. If the instructions on the pack specify a different amount or preparation step, use that instead.
For best flavor, use water that is hot but not necessarily boiling when it hits the cup; some botanical drinks taste smoother that way. You can adjust the strength to your preference: more water for a lighter cup, or a smaller amount of the mix for a milder taste. The drink is meant to be enjoyed as a warm beverage, so it is not intended to be consumed cold like a protein shake or juice.
If you are trying it for the first time, make one serving as directed and taste it before changing anything. The flavor is nutty and lightly spiced, with a forest-like note from cedar nut and warmth from turmeric. There is no need to add anything unless you want to, but if you usually sweeten your coffee, you can treat this drink the same way. Store the rest of the pack in a dry place with the package closed so it keeps its aroma and does not absorb moisture.
