Sweet potato overload

I was clearing weeds in the front yard to set a new landscape and found a patch of sweet potatoes. I just can't imagine ever running out of sweet potatoes as long as we keep throwing the harvested vines here and there like our cover crop seeds. After half a year or so when I remember the patch of sweet potatoes, just go dig them up. Each one will produce good 5 lb or so easily.

I started using sweet potatoes for edible ground cover since it's low growing and looks pretty attractive. Warm tropical place like Hawaii makes it easy to grow this. It's quick to fill in empty spot and smother out weeds pretty well. I imagine some of them are more than a year old and should be dug out for eating, but looking so nice and hard to disturb the garden.

Besides, we keep getting more sweet potatoes from random areas so unless I need the space for other special purpose, I can't think of a reason why i want to dig them up.

Green tea infused sake and avocado sashimi

Image
My favorite green tea and avocado combo is premium green tea infused sake and avocado sashimi.  Avocado is rich and creamy, and texture reminds me of toro, or fatty tuna and uni, or sea urchin. Mauna Kea Premium green tea is cold infused at room temperature for 5 hours in Kikusui junmai ginjo sake.  1 tablespoon (0.25oz) of green tea to 1/2 cup of this sake is a bit more than what I would use for brewing in hot water. I first got the idea of infusing green tea in alcohol from chemical analysis done at University of Hawaii, Hilo (UH Hilo).  They extracted and measured EGCg, Theanine and caffeine contents of green tea with boiling water, but what struck me was that their baseline concentrations of EGCg, Theanine and caffeine were extracted with methanol for 1/2 hour. MK premium Green extraction Theanine % Caffeine % EGCg % Boiling water 0.45% 0.35% 0.83% Methanol 0.11% 0.28% 1.73% High level of EGCg makes alcohol extraction bitter? Methanol extraction showed high level of

Tea, Pests, Disease and Pesticides, Hidden truth of unknown cause.

We hear quite a few incidence of pesticide contamination from Chinese tea.  One might wonder what is really happening with tea grown in China or anywhere else.  I remember a lot of farmers in Japan telling me that tea always attracts pests, and pesticides and tea are always inseparable.  Although it sounds like a reasonable excuse for tea farmers, but I believe there is much deeper cause of this tea, pest and disease relationship. Tea, pests, disease and pesticides are almost always big topics among tea farmers.  Because there are pests and disease, farmers have to spray or else they lose the crop or the harvest will be heavily damaged.  So the farmers go out and spray once, twice, three times.... and on and on until they are through with their annual cycle.  In Japan, some tea farmers brag about only spraying 5-6 times in one year.  They are considered eco-farmers. In my past 7 years of tea cultivation, there has never been a time I had to spray.  Should I say, I intentionally let

Red Bean Bread - anko remix

Image
I was going to make anko from azuki red beans and honey or cane sugar, but I didn't cook beans long enough so that it was still crunchy. Generally it gets soft all the way much like re-fried bean. Anyway, instead of using this red bean chunky mush as anko, or red bean filling in a bun, I mixed it in a dough. Here is the recipe. 4 cups flour (3:1 ratio of white and whole wheat) 1 1/2 cups water 1/2 tablespoon commercial yeast or use your own yeast culture 2 teaspoon salt 1/2 cup olive oil 1 cup chunky red bean paste 1 teaspoon ginger powder black sesami seeds note that there is no sugar added to yeast to rise. Instead of adding sugar, I use 1 cup flour, salt, ginger powder, olive oil and yeast mixed in 1 1/2 cup water and let it rise at 90 - 100F in an oven for 60 - 90 min. Once it gets a little bubbly, add the remaining flour to the mix and keep kneading. Also mix in the red bean paste once the dough starts to get more maneuverable without sticking to your hands too much. Make
