- Purging sand: Essential to avoid gritty bites-keep clams in cold salted water and change the water once during purge.
- Miso varieties: While white miso offers a mild sweetness,try blending with red miso for a deeper umami dimension.
- Make ahead: Prepare the dashi stock in advance and keep chilled. Assemble the misoshiru just before serving to enjoy optimal flavor.
- Texture balance: Incorporating soft tofu and crisp green onions adds gratifying contrast and enhances the comforting sip.
