Cornichon? in Cooking Posted September 26, 2015 This is late - but I look at old posts for answers so... You don't need French varieties - any pickling cuke will work, just use the very smallest of these. I have grown the French (Paris Pickling) cultivar, which is the most common 'cornichon' type, and it is really similar to other cultivars of pickling cukes. I just bought some at the local farmers market, and picked out very small (for cornichon) and larger (for 'Kosher Dills"). In addition cornichon (little horn) just means pickle - so some are not the type you might expect. Unless you want sweet or dill types (even French brands), look in the ingredients, which should not have sugar, and should contain tarragon for the type mentioned here.
