The citrus and anise flavours complement the salmon perfectly. Slow baking ensures the flavours meld, yet the salmon remains moist and succulent. The citrus butter sauce further enhances the flavour, while adding a creaminess to the texture as only a beurre blanc style sauce can.
On the three key components…
First, slow baking the salmon with fennel and orange. The fennel was seared to par cook it, but also to add another dimension to the flavour. The fennel and orange were layered, though the orange pieces could have been halved or quartered and mixed together with the fennel before laying the salmon pieces on the top. After seasoning and drizzling some olive oil, wrap it all up….
The citrus butter sauce draws on the beurre blanc tradition, but takes a lightly different approach by starting with a velouté sauce, then whipping in the cold butter. This made a larger quantity of buttery flavorful sauce, while using less butter to get the volume.
I found the spirulina pasta in a local deli. It had been produced in Thailand. While very tasty and great looking, and bringing along spirulina’s great health benefits, it may be difficult to find. Any good linguine will work, but a colored one will help visually highlight the fennel.
The recipe mentions retaining the salmon skin and frying it until crispy for a garnish. It is conspicuously missing from the photo above because my daughter ate it all before plating! It would have been a great garnish.
Another slow baked salmon recipe you may wish to take a look at is this one with couscous and various dried fruits and nuts.
