What about a chicken tagine with rhubarb? Start by poaching some rhubarb. Combine 1 1/4 cups water and 1 cup sugar in a medium saucepan. Add vanilla seeds and pod. Bring to a boil over medium heat, stir until sugar dissolves and add 2 cups diced rhubarb. Reduce heat to low and gently simmer rhubarb for 5 minutes, or until it can be easily pierced with the tip of a knife but remains intact. Do not overcook or else rhubarb will fall apart. Strain rhubarb over a bowl. Put the syrup aside to use another day.
Pour off all but 2 tablespoons of fat from the Dutch oven and add 1 finely chopped onion. Reduce heat to medium and cook, stirring and scraping the bottom of the pan to deglaze, until onion begins to soften, 2 to 3 minutes. Add 1 each of finely chopped carrot and leek. Cook, stirring often, for 3 to 4 minutes until vegetables are tender. Add a clove of crushed garlic and cook, stirring, about a minute. Add 1/2 tsp turmeric and 1 tsp sweet paprika and stir.
Return chicken to Dutch oven and add 1 cup chicken stock, 1 cinnamon stick, 1/2 tsp sugar and salt to taste. Bring to a simmer, then reduce heat, cover and simmer 35 minutes. Add 4-6 pitted green olives then cover and simmer another 15 to 20 minutes, or until chicken is falling off the bones. Stir in 1 to 2 tablespoons of the rhubarb syrup. Season to taste.
Before serving, stir in parsley and 1 cup of the poached rhubarb and heat through over low heat. Serve with rice or couscous.
First I made a rhubarb spoom. Yes that is a thing. Cut about 4 stalks of rhubarb into 2 cm lengths and put in a saucepan with 1/2 cup water and 1/2 cup sugar (or less according to your taste). Heat gently until the sugar is dissolved, bring to the boil and simmer covered until the rhubarb is tender about 5 minutes. Cool and puree until very smooth then chill completely. Stir in 1 tbsp rosewater. Beat two egg whites until they form soft peaks. Add 2 tbsp sugar and beat until you have stiff peaks. Now this is the magic. Fold the egg white into the puree making sure they are completely mixed. Transfer to a freezer-proof container and freeze for four hours. You now have a smooth creamy mixture that contains no fat and has not required churning.
Finally, I roasted some rhubarb. Cut about 8 stalks of rhubarb into 6 cm pieces and place in a medium bowl. Finely grate the zest of half an orange over the rhubarb and then squeeze the juice of the whole orange into the bowl. Split 2 vanilla beans and scrape out the seeds and place both in the bowl. Add 2 tbsp liquid honey and stir to combine. Pour the rhubarb into a baking dish and arrange the pieces so that they lie flat. Bake at 175 for 15 to 20 minutes. Remove the vanilla pods. Serve the rhubarb and the spoom with the syllabub from October 2014.
