    History of Tempura

    The tempura-style batter is said to have been brought to Japan by Portuguese missionaries in the 16th century, during the Muromachi period. However, as the cooking method of ‘deep-frying with flour batter’ was already established in Japan beforehand, the origin of tempura has been confused for a long time.

    There are also a number of theories surrounding the etymology of tempura, which adds to the dubiety. Some sources believe the word tempura comes from ‘tempero’, which means ‘seasonings’ or ‘spices’ in Portuguese, while some cited the definition from Kanji (Japanese-Chinese characters).

    What’s evident is tempura started to spread as street food and became a favorite among the common people in the early Edo period. With the increase of oil production, food stalls started selling tempura as a skewered snack food, alongside soba, sushi, and eel. By the late Edo and early Meiji era, tempura shops and restaurants emerged and started establishing its position as a specialty cuisine.

    Today, you can find some best tempura houses in Japan, where all of your meals will be cooked by a highly trained chef who devotes his entire careers in tempura frying.

    It cannot be any more true to say that tempura is one of Japan’s representative dishes.


    What Ingredients to Use for Tempura

    You can basically make tempura with a wide range of fresh ingredients, with the most common options that include seafood and root vegetables. There are also local tempura menus all over Japan that feature seasonal ingredients unique to the area.

    Seafood

    The most popular tempura is, of course, Shrimp Tempura, also called Ebi no Tempura (海老の天ぷら) or Ebi Ten (えび天). In Japan, we use Japanese tiger prawns or Kuruma Ebi (車海老) that are large in size and have a sweet, buttery flavor. In the US, you can use black tiger shrimp or jumbo shrimp for tempura.

    You can also find other seafood being fried up. Here are some of the delicious examples:

    • Abalone (鮑, あわび)
    • Barracuda (梭子魚, かます)

    Vegetables, Mushrooms & Seaweeds

    For vegetable tempura, root vegetables such as sweet potato, Kabocha squash, and lotus roots are most ideal. Other popular ingredients such as Japanese mushrooms (shiitake and oyster), eggplants, okra, shiso leaves, and shishito peppers are also suitable for frying in the batter. In rural Japan, people even fry up wild edible plants and shoots like dandelion and fiddleheads for tempura.

    When choosing vegetables, you’d want to avoid vegetables with high water content such as tomato, celery, and cucumber. They do not hold up the batter well, and the moisture will result in the vegetables getting burnt easily.

    Here are some of the popular vegetables, mushrooms & seaweeds for tempura:

    • Asparagus (アスパラガス)
    • Avocado (アボカド)

    How to Make The Best Tempura Batter 

    Tempura – How to Make Best Tempura | Easy Japanese Recipes at JustOneCookbook.com

    The success of your tempura is in the batter. To achieve the crispy texture, it’s very important to minimize the gluten formation in the batter as much as possible. Below are the tips to follow:

    • Choice of flour – All-purpose flour is the most basic flour for tempura batter. Some people prefer using low-protein flours, such as cake flour or a mix with corn starch. For convenience, there is also a pre-mix tempura flour available. Personally, I always make my tempura batter from scratch using all-purpose flour, iced water, and egg.
    • The recommended flour to water ratio is 1:1. 
    • A cold batter is absolutely necessary – Make sure all your ingredients (flour, water, egg) are cold. Keep your water refrigerated so it’s icy cold. This helps the batter cling on to the surface of the ingredients.
    • Do not overmix the batter –  Use chopsticks to mix for only a few seconds to at most a minute. It’s even helpful to leave some floury lumps in the batter. A lumpy batter contains more air and irregularities, which gives the tempura a light lacy layer that we’re after.
    • Aim for consistency – The finished batter shouldn’t be too thin or too thick. I’ll go for a heavy cream consistency.
    • Make batter right before you deep fry to reduce gluten activation.

    The Deep Frying Technique

    Tempura – How to Make Best Tempura | Easy Japanese Recipes at JustOneCookbook.com

    In Japanese cooking, deep frying is an art, and it takes some know-how and practice to execute desirable results. For the case of tempura, the hot oil enhances the natural sweetness and flavors of whatever you’re frying, at the same time, devoid of greasiness. Let’s take a look at how you can achieve that at home:

    • Type(s) of oil for frying –  Most tempura restaurants use untoasted sesame oil or their own special blend of oil. At home, you can also use a neutral-flavored oil such as vegetable or canola oil and simply add a touch of sesame oil for a deliciously nutty aroma.
    • Ideal oil temperature for frying –  Depending on the ingredients, we are looking at the range of 320-356°F (160-180°C).
    • Keep the oil temperature steady at all times.
    • Do not overcrowd the frying pot with ingredients – As a rule of thumb, only half of the oil surface should be covered with ingredients.  So, deep fry in batches.
    • Use a thermometer for precise temperature control, especially if you’re not familiar with deep frying.
    • Turn the tempura regularly to ensure even cooking.
    • Pick up crumbs in the oil between batches – You wouldn’t want any burnt crumbs to attach to your new tempura pieces or dilute the oil flavor.

    How to Make The Best Tempura Dipping Sauce

    Tempura is the best when you dip them in the delicious Tentsuyu (天つゆ) or Tempura Dipping Sauce. The sauce itself is delicate but has all the sweet-savory flavor you need to accentuate the enjoyment of fresh, hot tempura.

    The sauce is made with 4 simple ingredients:

    1. Dashi
    2. Soy sauce
    3. Mirin
    4. Sugar

    The same sauce can be used for donburi (rice bowl dishes), soba and udon noodles, simmered dishes (nimono), and many Japanese dishes.

    The tempura dipping sauce can be put together quickly. When you made homemade dashi (either from scratch or from the convenient dashi packet/powder), save a portion to make the sauce. It will be ready in less than 5 minutes!

    Here’s my Tentsuyu (Tempura Dipping Sauce) recipe.

    Serve the hot-off-the-frying-pot tempura with tentsuyu dipping sauce along with the grated daikon that helps refreshen your palate. It makes a remarkable main dish to enjoy on its own.

    Tempura also goes well with flavored salts such as matcha salt, yuzu salt, and curry salt.
