Splake is a hybrid species of brook trout crossed with lake trout; it has a mild, slightly buttery flavour. As a cold-water fish in the trout family, it also contains some of the same heart-healthy omega-3 fatty acids. Pair it with this highly flavourful beet sauce and tender-crisp carrots and you have a dish with a fetching presentation worthy of even the fanciest restaurants.
Outside of Ontario, splake can be hard to come by, so consider fillets of arctic char, rainbow trout, steelhead, or wild salmon as great substitutes.
Extra pesto can be stirred into pasta. It also makes for a standout sandwich spread.
Per serving:
Preheat oven to 400 F (200 C). Toss beets with 1 tsp (5 mL) oil. Place on sheet of parchment paper and wrap tightly to seal. Place on baking sheet. Place in oven and heat until beets are tender, about 25 minutes. Remove from sheet and set aside until cool enough to handle. Peel, then chop into 1/2 in (1.25 cm) pieces.
Blend cooked beets in food processor container with dill, horseradish, garlic, lemon juice, and salt. Wipe down sides of container and then, with machine running, pour 3 Tbsp (45 mL) oil in through feed tube until incorporated. Set aside.
Line baking sheet with parchment paper large enough to hold fish and carrots in a single layer. Toss carrots with 2 tsp (10 mL) oil and place on sheet. Bake in preheated oven for 30 minutes, or until they begin to colour and are starting to slightly golden. Remove from oven and slide carrots to the side using a spatula. Place fish on pan. Season with salt and pepper, to taste.
Return pan to oven and bake for 12 minutes, or until fish is just cooked through in the centre and carrots are tender.
Place fish and carrots on serving platter and scatter with beet pesto and almonds.
