Homemade dashi stock is a Japanese broth recipe made with kombu and bonito flakes to create clean umami flavor for soups, noodles, sauces, and simmered dishes. The first extraction usually starts by soaking kombu, warming it gently, then adding bonito flakes off the heat so the broth stays clear, fragrant, and delicate. Instead of throwing the ingredients away, they can be used again for a second dashi by simmering them with fresh water and extra bonito flakes to make a lighter but still useful stock. This second extraction helps stretch the ingredients and makes the recipe more practical for everyday cooking. The final dashi can be used for miso soup, udon, soba, ramen, tamagoyaki, chawanmushi, donburi, and Japanese sauces with a clean savory base.

00:00Ever thought about what creates the depth in Japanese food?
00:03The answer is dashi stock.
00:05And in this video, I'm going to show you how to make a basic awasedashi
00:09made with two key ingredients, dried beneath flakes and konbu kelp.
00:14Watch until the end for extra tips on how to make the most of your ingredients
00:19and time-saving budget-friendly alternatives to homemade dashi.
00:23You can also find this recipe on my website along with 400 Japanese recipes.
00:27Just google awasedashi's space sedachi to find the written recipe.
00:32I'm going to start by placing 5-10g of konbu in a pot.
00:36There are all kinds of kelp out there, from the cheap kind to the premium kind.
00:41But when it comes to everyday home cooking, hidaka konbu is the best choice.
00:46Here's a tip too, don't wash your konbu.
00:49You might know it's a white powdery coating on the surface,
00:52but it's actually a natural flavour enhancer made of glutamic acid and mannitol.
00:58If you spot any sand or dust, just gently wipe off with a damp cloth instead of washing.
01:05Pour one litre of cold water into the pot.
01:08For the best results, use soft water.
01:10Soft water effectively extracts umami from konbu and dried beneath flakes.
01:15Soak the konbu in the water to rehydrate it.
01:19This will take at least 30 minutes, but you can soak it for up to 24 hours if you got
01:25the time.
01:25I use 10g but you can use less.
01:29Just keep in mind that with less konbu, you won't soak it longer.
01:33If you're soaking it for more than a few hours, just cover it and put it in the fridge.
01:39After the extraction, put your pot on medium low heat and let the konbu and water warm up gradually.
01:45This gentle heating process takes about 10 minutes, but trust me,
01:50it's worth the patience to extract those rich flavours.
01:54Watch the edges of your pot for tiny bubbles starting to form.
01:58Also, don't let it boil.
01:59Boiling konbu will release bitter compounds and we definitely don't want that.
02:04Once you spot those tiny bubbles around the edges of your pot, it's time to take out the konbu.
02:15Remove the konbu when the water reaches between 60 and 64 degrees Celsius, which is 140 to 150
02:24Fahrenheit, which is basically when small bubbles start to appear.
02:30Then turn up the heat medium and let the liquid come to a boil.
02:35This quick boiling step helps get rid of any strong kelp smell.
02:39Just keep an eye out for any form of scum on the surface and if you see any,
02:44simply skim it off with a fine mesh strainer or spoon.
02:48This will ensure your dash is nice and clear, not cloudy.
02:52Now, pour in 100 milliliters of cold water.
02:55This replaces the water the konbu absorbed and helps lower the temperature a bit.
03:01Turn the heat down to its lowest setting and gently add two handfuls of your bonito flakes.
03:06Make sure to let those flakes sink naturally.
03:09Resist the urge to stir or poke them.
03:12Give them 3 minutes to steep.
03:14If your stove is a bit temperamental with the low heat, no worries.
03:18You can just turn it off completely and let the bonito flakes steep for 5 minutes instead.
03:23Awasedashi is special because it's like a perfect band where every instrument plays its part just right.
03:30It doesn't overpower your dish.
03:31Instead, it creates this amazing umami foundation that makes every other ingredient shine.
03:37To be more specific, the rich umami comes from glutamic acid from konbu and inosinic acid from katsuobushi.
03:45Finally, let's strain the dashi.
03:47Grab a fine mesh sieve and line it with either a piece of cheesecloth or paper towels.
03:53Set it over a heatproof bowl.
03:55Pour your dashi through this setup which is important for getting that beautiful clear broth since those
04:02bonito flakes are really fine.
04:10Resist the urge to squeeze or press those strained bonito flakes.
04:13I know it's tempting but this will only release bitter compounds and mess with the delicate flavours
04:19we've worked so hard to create.
04:22Did you know you can actually make dashi twice from the same ingredients?
04:26Just like squeezing a second cup from a single tea bag.
04:30This first extraction is called Ichibandashi and Nibandashi for the second.
04:36By the way, if you want to make the most of your fresh Ichibandashi and make a clear soup,
04:41take 300ml of your strained dashi and combine it with 1.4 tsp of sea salt, 1.5 tbsp of
04:48sake,
04:49and 1.5 tsp of usukushu shoyu. That's Japanese-like soy sauce.
04:54Just warm this mixture over low heat for about 2 minutes. This quick step helps all those flavours
05:00come together beautifully.
05:01Now let's make sure we get our money's worth with our second extraction.
05:06Use the kombu and bonito flakes from your first dashi and put them back in the pot.
05:13Add 1 litre of fresh water and toss in another handful of fresh bonito flakes.
05:20Put it over medium heat and let it come to a boil.
05:25Once it's boiling, turn the heat down to medium low and let it simmer for 10 minutes.
05:30If you see any foam or scum floating up, just skim it off.
05:34Unlike our first dashi where we have to be very careful,
05:38this second extraction actually gets better with a longer simmer to extract all those remaining flavours.
05:45Finally, strain everything again, just like before.
05:48Unlike our first dashi where we have to be gentle,
05:51you can actually press and squeeze these solids to get every last bit of flavour out.
05:56So go ahead, no need to be shy about it this time.
06:00We want to extract all those remaining flavours.
06:03I recommend letting it cool first though.
06:06I lived in England for several years so I totally get how expensive
06:10bonito flakes and kombu can be outside of Japan.
06:13In restaurants in Japan, these ingredients are used generously because dashi is their lifeline.
06:19But here's the thing, you don't need restaurant quantities at home.
06:23Like even now that I'm back in Japan,
06:25I'll still catch myself wincing when measuring out lots of katsubushi.
06:29You can still make grey dashi with more modest amounts.
06:33This recipe is optimised for home use and remember,
06:36it's all about finding a balance that works for your budget and cooking style.
06:41There's no point if it's not sustainable.
06:44If you're planning to store dashi and use it within a week, the fridge is your best bet.
06:49Just remember to let your hot dashi cool to room temperature first,
06:53then pour it into an airtight container or jar.
06:57If you're planning on storing it for a while, let it cool completely,
07:02seal it up in an airtight container and it'll keep in the freezer for up to a month.
07:08In fancy Japanese restaurants, Ichiban dashi and Niban dashi have very different roles.
07:13Ichiban dashi is the premium ingredient.
07:16It's delicate and perfect for clear soups where every subtle flavour counts.
07:21It's a huge deal.
07:22In fact, a head chef with over 30 years of experience told me
07:27that first extraction is the most nerve-wracking part of his workday.
07:32Then we've got this Niban dashi.
07:34It might not be as fancy as Ichiban dashi,
07:37but it's perfect for heartier dishes like meat soup and simmered foods.
07:41But you don't need to think too much about it for home cooking.
07:45One more tip before I go.
07:47You don't always have to make dashi from scratch.
07:50There are some easy alternatives like granulated dashi and dashi packets which look like teabags.
07:57In my opinion, when I need dashi as a base flavour for soup, noodles or hot pot dishes,
08:03I much prefer teabag style dashi packets over granules.
08:07Why?
08:08Granules can often make the flavour a bit blurred when you use a lot of them
08:13since they contain various ingredients and additives.
08:16But teabag dashi packets have a cleaner taste at least.
08:20That said, I do reach for the granules when I just want to add a quick touch of Japanese flavour
08:26to stir-fries or other non-soupy dishes.
08:30Of course, your options might be limited depending on where you live.
08:34Sometimes granules are all you can find.
08:36That's totally fine.
08:37The best method is the one that works for you and your kitchen.
