I had a plan to visit the university alumni friend who was hospitalized @her assist living.
I harvested a lots of red shiso from garden, I made shiso juice for her.
I scaled them and I got about 3kg shiso leaves.
Boil for few minutes.
Red shiso’s purple color changed to green after boiled.
The boiling liquid colored dark purple. Add brown sugar, and vinegar.
This is red shiso juice, very pretty purple color.
