1. Cautions for Food Ingredients

(1) Food ingredients to be eaten raw

E.g. raw eggs with sukiyaki, sashimi

On Cookbook, we also introduce common recipes in Japan that use ingredients to be eaten raw. However, the handling of eggs, fish and other such ingredients often eaten raw in Japan varies by country and region, and as such there are instances where eating these raw is not recommended. As noted in cautions for each recipe using ingredients to be eaten raw, we ask you to adhere to the guidelines provided by your local Food Safety Information Center when using these types of ingredients.

  • *Seafood ingredients indicated as “sashimi-grade” in recipe ingredient lists are intended to be eaten raw.

(2) Dishes that are complete when partially cooked

E.g. poached eggs, roast beef

There are some foods that are complete when partially cooked. As mentioned in (1), we recommend that you adhere to the guidelines provided by your local Food Safety Information Center when cooking with these types of ingredients.

(3) Alcohol used in cooking

E.g. mirin, sake

In Cookbook recipes, the common Japanese seasonings of “mirin” and “sake(cooking sake)” are often used. Both of these seasonings contain alcohol. Please refer to information in the links for alternatives.

(4) Ingredients to be avoided

For our selection of recipes, please confirm the recipe contents, obtain the required ingredients and cook these yourself.

2. Cautions for Cooking and Preparation

(1) When using plastic bags and plastic wrap

Please confirm resistance to hot and cold temperatures. Also check that these are microwave safe and be careful not to overheat when using in a microwave.

(2) About measurements

Please refer to Weights and Measurements for measurement unit conversions.

(3) When using a microwave

Many of our recipes use a microwave at 600W (or 500W). Please note that the higher the wattage, the shorter the required heating time.

E.g. 1 min at 600W = 50 secs at 800W, 40 secs at 1000W and 30 secs at 1200W

Please confirm the heat resistance temperatures of plastic wrap and containers when using in a microwave.

(4) About recipe contents

We do not use acute accents in our recipes.

E.g. saute, sauteed, puree, glace

Also, Celsius is indicated with ℃, and Fahrenheit is indicated with F.
