            1        
        
            Season chicken generously with salt and pepper. Dust lightly with flour and shake off the excess.        
     
    
        
            2        
        
            Melt butter in a large, heavy-bottomed pot or skillet that's set over medium-high heat. Sauté chicken in batches if necessary, until well-browned and crisp on all sides. Set aside.        
     
    
        
            3        
        
            Add the whole shallots to the pot and sauté them in the butter and chicken fat until they begin to soften and caramelize, about 10 to 12 minutes.        
     
    
        
            4        
        
            Add wine to deglaze the pot, scraping up any of the browned bits with a spoon and then add mustard and tarragon.        
     
    
        
            5        
        
            Add chicken back to the pan, skin side up. Simmer covered over low heat for 30 minutes.         
     
    
        
            6        
        
            Remove lid and add in cherry tomatoes. Continue to simmer uncovered allowing the sauce to reduce a little. Season to taste.
