Healthy Rooibos Poached Salmon with a Lemon Honey Vinaigrette

Poaching salmon in rooibos gives you a result that’s hard to beat: moist, delicate fish with a subtle earthy sweetness from the tea and a gentle amber colour. Add honey, lemon and peppercorns to the broth and it becomes genuinely aromatic. The whole thing takes about 15 minutes, start to finish.

I finish this with a classic lemon vinaigrette, sharp and bright against the soft fish. It’s one of those combinations that looks like effort but isn’t.

Why poach salmon in rooibos?

Rooibos has a naturally sweet, slightly woody flavour with none of the tannin bitterness you’d get from black tea. That makes it ideal as a poaching liquid: it adds something without overpowering the fish. The salmon takes on a warm reddish tinge from the tea, which looks beautiful on the plate.

If you like the idea of tea-poached salmon, the lapsang souchong version takes things in a smokier, more Asian direction and is worth trying too.

How to poach salmon perfectly

The key is keeping the liquid at the gentlest possible simmer. You want to see just the occasional small bubble, not a rolling boil. Vigorous boiling breaks up the flesh and toughens the fish. If you’re nervous about the heat, bring the broth to a simmer, add the salmon, and then turn the heat off completely. The residual heat will cook it through; it’ll just take a few minutes longer.

Bring the salmon to room temperature before you start. Cold fish straight from the fridge will need longer and can cook unevenly.

The broth here is enough to poach 2 large fillets, or up to 800 grams of fish. Scale the salmon to however many people you’re feeding.

The lemon vinaigrette

This is a simple Dijon vinaigrette with a little honey to round it out. Shake everything in a small jar until it thickens and emulsifies. You can use a little of the lemon from the poaching liquid for the juice, which ties the flavours together nicely. Drizzle it over the warm fish and the greens just before serving.

What to serve with rooibos poached salmon

Steamed asparagus is the classic match here. Baby spinach leaves dressed in the same vinaigrette work well alongside. Broccolini, sugar snap peas or bok choy all pair well too. Keep the sides simple so the fish stays the centrepiece.

FAQs for tea poached salmon

What does rooibos taste like in a poaching liquid?

Rooibos has a mild, slightly sweet, earthy flavour. It’s caffeine-free and has no bitter tannins, which makes it gentler than black tea as a cooking liquid. In a poaching broth it adds warmth and colour without sharpness.

Can I use rooibos tea bags instead of loose leaf?

Yes. Brew 3 to 4 tea bags in 750ml (3 cups) of just-boiled water for 5 minutes until very strong, then remove the bags before adding the other broth ingredients.

How do I know when poached salmon is done?

Press the thickest part gently. When it flakes easily and the flesh is opaque all the way through, it’s ready. For a slightly softer, just-cooked centre, check at 5 minutes. For fully cooked, go to 8 minutes depending on the thickness of the fillet.

Can I serve this cold?

Yes, it’s excellent cold or at room temperature. Keep it covered in the fridge and serve within 2 days. The vinaigrette works just as well on cold salmon.

Prep Time:15 minutes mins

Cook Time:10 minutes mins

Ingredients

Poaching broth

• 350 to 800 grams salmon fillet skin on and pin-boned, at room temperature
• 750 ml 3 cups strongly brewed rooibos, hot
• 1 lemon sliced
• 60 grams ¼ cup honey
• 1 tsp whole black peppercorns
• 1 Tbsp sea salt flakes

Lemon vinaigrette

• 1½ tsp Dijon mustard
• 1 tsp honey
• 60 ml ¼ cup extra virgin olive oil
• 2 Tbsp white wine vinegar
• 1 Tbsp lemon juice
• Pinch of freshly ground black pepper and sea salt flakes

Instructions

• Brew the rooibos strong and pour it into a wide, shallow pan. Add the lemon slices, honey, salt and peppercorns. Bring to a gentle simmer over low heat.
• Slide the salmon into the broth skin side up. Keep the heat low — you want a barely-there simmer, not a boil.
• Poach for 5 to 8 minutes depending on the thickness of the fillet. About three-quarters of the way through, flip the salmon and check for doneness. The fish is ready when it flakes easily at the thickest point.
• Remove carefully with a slotted spatula and drain on a paper towel.
• Place all the vinaigrette ingredients in a small jar and shake vigorously until emulsified. Drizzle over the warm fish and any greens alongside.

Notes

Serving: Steamed asparagus and baby spinach leaves dressed in the vinaigrette make the ideal accompaniment.
