There are three other cooking supplies or ingredients stores in the same neighborhood as E. Dehillerin, and they are so close together that visiting all of them in one morning or afternoon is easily done. The three other shops are far less “intimidating” and a little more modern than Dehillerin, but they also lack “gravitas”…
Mora has lots of baking related items including baking cups, molds, decor of all types as well as dragees, colored sugars, etc. I found a really nice olive oil bottle and pourer for Euro 10 or so, and I also got more silpat silicone baking mats.
A stone’s throw away is A. Simon, that has more cookware and lots of tableware, I think predominantly aimed at restaurateurs.
Many of the items on offer are made in France, or Europe, and I particularly liked the REVOL brand ceramics on offer.
And finally, you may want to look in on La Bovida, for spices, oils, vinegars, etc. Except I have to warn you, the Piment d’espelette that I bought here could be had for half the price nearby. So it’s overpriced and the least impressive of all the stores mentioned.
