FAQ

Common questions

How do I best freeze fresh herbs?+

Wash the herbs, dry well and chop finely. Fill the cavities, top up with a little olive oil or water and freeze. Once frozen, push out the cubes and store them in a container. This keeps basil, parsley and chives for months.

Which herbs are good for freezing?+

All soft herbs: basil, parsley, chives, coriander, dill, mint. Hard herbs like rosemary and thyme dry better. Herb ice cubes are perfect for finishing sauces, soups and risotto.

Can I also use the Helmu for baking?+

Yes - 30 ml is ideal for mini muffins, small brownies, madeleines or mini quiches. Oven-safe to 250 °C, the bake releases easily - no greasing needed.

How big are the ice cubes?+

Each cube holds 30 ml - larger than standard ice cubes. Bigger cubes chill drinks longer without watering them down. Also ideal for cubes with lemon, mint, cucumber or berries.

How do I portion pesto or sauces?+

30 ml is one pesto portion for a single person. Simply freeze, take out portion by portion and thaw in the fridge or add straight to hot pasta.

Is the mould suitable for herb butter?+

Yes - mix soft butter with herbs, fill the cavities, freeze. Push out the finished herb-butter cubes and store in a bag. Always to hand for steaks, pasta or bread.

Does a lid fit the Helmu?+

Yes - every Helmu comes with a matching lid. This prevents freezer burn and the cubes don't absorb odours from the freezer.
