Frequently Asked Questions

Q: How do I use the triangular sushi rice ball mold to make onigiri?

A: Using the triangular rice ball mold is simple. Wet the inside of the mold lightly to prevent sticking, then fill it halfway with seasoned rice. Add your desired filling in the centre (tuna, pickled plum, salmon, etc.), then cover with more rice. Place the lid on top and press firmly. Slide the lid off, then push from the bottom to release your perfectly shaped triangular onigiri. Wrap in nori (seaweed) if desired and serve!

Q: Is the mold safe for use with hot, freshly cooked rice?

A: Yes. The mold is made from food-grade PP (polypropylene) plastic, which is designed to handle warm foods safely. For best results, allow freshly cooked rice to cool for 1–2 minutes before filling the mold so it is easier to handle and shapes more neatly.

Q: Can children use this sushi rice ball mold?

A: Absolutely! The mold is designed to be simple and intuitive, making it a fantastic activity for children and beginners. Supervised use is recommended for young children. It's a wonderful way to get kids involved in meal prep and excited about trying new foods.

Q: How do I clean and store the onigiri mold?

A: Hand-wash the mold with mild dish soap and warm water after each use. The smooth PP surfaces make cleaning quick and easy. Allow to air-dry completely before storing. Avoid abrasive scrubbers or harsh chemicals to preserve the mold's surface over time.
