Yum Woon Sen: Wild-Caught Mackerel & Glass Noodle Salad
A vibrant, zesty Thai salad where chewy glass noodles are tossed with seared wild mackerel, crisp cucumber, and an explosion of fresh cilantro and mint. The dressing relies on the umami depth of high-quality fish sauce and the bright acidity of lime, sweetened only by a whisper of ripe date syrup to balance the heat without spiking blood sugar.
A little context
Yum Woon Sen is a staple of Thai 'Yum' (spicy salad) cuisine, traditionally balancing hot, sour, salty, and sweet. We honor this tradition by keeping the protein wild and the noodles pure mung bean, but we strip out the refined palm sugar and the common practice of frying the noodles in seed oils. Instead, we blanch the noodles in a savory bone broth and dress them with extra-virgin olive oil and fresh aromatics, creating a dish that respects the palate while aligning with modern longevity principles.
The longevity story
This dish is a polyphenol powerhouse built on the synergy of wild-caught fatty fish and fresh herbs. The wild mackerel provides high levels of EPA and DHA omega-3s, essential for reducing systemic inflammation and supporting cognitive longevity. The dressing's garlic and shallots offer allicin and quercetin, while the massive volume of cilantro and mint introduces digestive-supporting flavonoids. We eliminate the traditional palm sugar spike by using a minimal amount of date syrup, which provides sweetness alongside fiber and minerals, ensuring a stable glycemic response.
Method
- 01
Prepare the broth and noodles
Bring 2 cups of homemade bone broth (or unsalted chicken stock) to a simmer. Add the soaked glass noodles and cook for 3-4 minutes until they turn translucent but remain chewy. Drain immediately and rinse under cold water to stop cooking. Toss lightly with 1 tsp of the olive oil to prevent sticking.
- 02
Sear the mackerel
Pat the wild mackerel fillets completely dry. Season liberally with sea salt. Heat a cast-iron skillet over medium-high heat with 1 tbsp of avocado oil. Sear the fish skin-side down for 3 minutes until crisp, then flip and cook for 2 minutes more until just opaque in the center. Let rest for 5 minutes, then flake into large chunks, removing any bones.
- 03
Make the dressing
In a small bowl, whisk together the fish sauce, fresh lime juice, minced garlic, julienned ginger, and date syrup (if using). Slowly drizzle in the remaining extra-virgin olive oil while whisking to create a loose emulsion.
- 04
Assemble the salad
In a large mixing bowl, combine the cooled noodles, flaked mackerel, sliced cucumber, red onion, chilies, cilantro, and mint. Pour the dressing over the top.
- 05
Toss and serve
Gently toss the salad with tongs, being careful not to break up the fish too much. Taste and adjust with more lime or a pinch of salt if needed. Serve immediately at room temperature or slightly chilled.
Pro tips
- ✦Source your mackerel from a fishmonger who can tell you the catch date; wild mackerel spoils faster than farmed varieties, so freshness is non-negotiable.
- ✦Do not overcook the glass noodles; they should have a slight bite (al dente) as they will continue to absorb the dressing.
- ✦Crush your garlic and let it sit for 10 minutes before adding to the dressing; this activates the enzyme alliinase, maximizing the allicin content for gut health.
- ✦If the salad sits for more than 20 minutes, the noodles will absorb the liquid. Add a splash of fresh lime juice or broth before serving to refresh the texture.

Substitutions
- wild-caught Pacific mackerel → wild-caught Arctic char or rainbow trout (These fish have similar fat profiles and hold up well to searing, though mackerel is the traditional choice for its distinct flavor.)
- date syrup → 1 tsp pure maple syrup or monk fruit sweetener (Use sparingly; the goal is to balance the acid, not make the dish sweet.)
- glass noodles → shirataki noodles or zucchini noodles (For a lower-carb, grain-free option, though the texture will be significantly different.)
Storage
Store in an airtight glass container in the refrigerator for up to 2 days. The noodles will absorb the dressing, so add a splash of lime juice or broth before serving. Do not freeze, as the texture of the fresh herbs and cucumber will degrade significantly.
What to serve with it
- Hot green tea (sencha or matcha) to complement the umami and aid digestion
- Sparkling water with a wedge of lime and fresh mint
- A glass of dry, light-bodied red wine like Pinot Noir (if alcohol is part of your routine)
- Serve alongside a small bowl of steamed jasmine rice if you need additional carbohydrates, though the dish is satiating on its own.
FAQ
Why use extra-virgin olive oil instead of sesame oil?+
Traditional Yum Woon Sen often uses no oil or sesame oil. However, sesame oil is often refined with seed oils, and high heat can degrade its polyphenols. We use EVOO for its high heat stability and massive polyphenol count, which aligns better with a longevity diet.
Can I make this vegan?+
Yes, substitute the fish sauce with a high-quality, fermented soy-free coconut aminos or a mushroom-based fish sauce alternative, and use smoked tofu or tempeh instead of mackerel.
Is the date syrup necessary?+
No. If your limes are very sour and the fish sauce is salty enough, you may skip the sweetener entirely. The natural sweetness of the onion and garlic often provides enough balance.
