To prepare it as a drink, add the instant chicory to a cup and pour over hot water, then stir until dissolved. Because this product is instant, it is made for quick preparation and does not need brewing, filtering or steeping. If you are unsure how strong you like the flavour, begin with a smaller amount and adjust in future cups; chicory has a roasted, mildly bitter character that can become more pronounced when made stronger.
For a smoother taste, prepare it with hot milk or a warm plant-based drink, or use a mix of water and milk. This can soften the bitterness and make the drink feel closer to a latte-style cup, while still remaining caffeine-free if your added ingredients are caffeine-free. Sweetening is optional and depends on your usual preference, but the product itself is best thought of as a roasted root drink rather than a sweet beverage.
You can also use instant chicory in desserts and baking where a subtle roasted note is welcome. For example, it may be stirred into liquid ingredients for cakes, creams or puddings, provided the recipe has enough moisture for it to dissolve evenly. Since it has its own bitterness, add gradually when experimenting so it supports the flavour rather than overpowering the recipe.
