Onsen Tamago
Make your eggs and egg dishes 10 times more valuable!
Onsen tamago is a Japanese name for soft-cooked eggs which are very popular either as stand-alone entries or additions to a variety of other dishes served in different cuisines. The eggs are cooked at a certain temperature to a degree where yolks and whites still remain soft and silky. Because of their taste and texture, these eggs create more value than when they are served hard-boiled or raw.
But there is, however, one problem – it is difficult to make them with consistency in quality and in large quantities.
When we make onsen-tamago eggs in bulk, it often results in inconsistent level of doneness. Some eggs are hard. Some eggs are not yet done. So, we would need to constantly check them to see if they are ready. Checking the doneness means cracking eggs open. It is a cumbersome, time-consuming and potentially wasteful task.
But now there is an efficient and low-cost solution to this problem. You can now make onsen tamago eggs in large quantities with ease and consistency.
Ontama Magic set lets you cook up to 80 onsen tamago eggs at a time with consistent doneness throughout whole volume in just 8 minutes (note: 8 minutes to boil 80 medium size eggs to the onsen tamago level of doneness; actual boiling time / number of eggs per batch will depend on the egg size).
With this tool you can start making and serving onsen tamago eggs at a professional-level quality and in commercially viable quantities.
