Juice the lemon. Mince the garlic. Peel, halve and mince the shallot. Pick the basil leaves off the stems. In a small bowl, combine the pesto with a drizzle of oil; stir to combine thoroughly.
In a medium pot, heat a drizzle of oil on medium-high. Add the rice, ½ the shallots and ½ the garlic. Cook, 30 seconds to 1 minute, until the rice is slightly translucent. Add the demi-glace and 3 cups water (5 ½ cups for 4 portions); season with ⅔ of the spice blend and S&P. Bring to a boil; reduce the heat and simmer, stirring occasionally, 12 to 15 minutes (16 to 20 minutes for 4 portions), until most of the liquid has been absorbed and the rice is al dente (still slightly firm to the bite).
While the risotto cooks, in a large pan, heat a drizzle of oil on medium-high. Add the tomatoes and cook, stirring occasionally, 4 to 5 minutes, until the tomatoes begin to burst; season with the remaining spice blend and S&P. Transfer to a bowl. Reserve the pan.
In the same pan, heat a drizzle of oil on medium-high. Add the remaining shallots and garlic. Cook, stirring frequently, 30 seconds to 1 minute, until fragrant. Add the baby kale and cook, stirring frequently, 1 to 2 minutes, until the greens have wilted; season with S&P to taste.
To the pot of risotto, add the cooked tomatoes, wilted baby kale, Parmigiano Reggiano, 2 tbsp butter (double for 4 portions) and 1 tbsp lemon juice (1 ½ tbsp for 4 portions); stir to thoroughly combine. Divide the finished risotto between your plates and drizzle with the pesto. Garnish with the basil (roughly chop before adding). Bon appétit!
