when you say "miso" do you mean "miso paste" ? Just trying to figure out what to purchase and where I can buy it. Thank you!

Miso is made as a paste so calling it "miso paste" is a bit superfluous, sort of like "pesto paste." The products on the store shelves will just be labeled "miso."

The flavor differences are largely personal taste. Different miso types feature more prominently in regional dishes; using a stronger miso in traditional Kyoto dishes would be considered peculiar.

This obviously is not a traditional Japanese dish, so miso selection here is even more dependent on your own personal preference.

Unquestionably, the best place to buy miso is in a Japanese grocery store. There one will find a large selection of various miso types: "shiro" (white, particularly popular in Kyoto), "aka" (red"), dark, and a few others.

Miso imported from Japan is better than domestically produced ones. The Japanese have been making miso for ten thousand years, they know what they are doing.

I have no specific brands to recommend but in a Japanese grocery store, the most expensive misos will be the best. Japanese customers aren't going buy something mediocre at a premium price, especially for something with long heritage like miso, an essential staple of their larder.

Happy shopping!

Hi Amy: yes, miso paste! It's often sold in tubs in the grocery's refrigerated section. The most common / easy-to-find varieties are white (shiro), red, and yellow. I most commonly buy white, which is a bit milder in flavor, but any variety will work in this recipe. And if you need ideas for how to use up the tub, check out this post! : ) https://food52.com/blog/21665-recipes-to-use-miso
