The short: "Bonne Maman Peach Compote" is the exact Peach sauce TJ's imported from France.
The long: We loved TJ's Peach Sauce and spent time tracking down the original supplier. The TJ jar says "Made in France" and the glass is imprinted with the name "Andros". Sure enough, Andros is a french company that makes fruit sauces. We emailed the company, they told us that the name of the sauce supplied to TJs is "Compotes de PĂȘches" (Peach Compote) and sold under the brands Andros and Bonne Maman, although the TJ's quality is Bonne Maman.
Where to find it? American Marketing team (www.worldfiner.com) exports it. Use their distributor list (http://www.worldfiner.com/distributors.html) to find a local distributor who can point you to a retailer.
We found a store online (search for "compote" at Spec's: www.specsonline.com) and ordered a case of 12 for $70 plus $30 shipping. Excellent service, but you'd be better off finding a local store, as shipping is expensive.
It's EXACTLY the same sauce, and so very nice to have again!
