Bacon, Cheese and Onion Tart

Since being home, I have been looking for arrowroot to use for thickening gravies and making batters for crispy coated veggies and the like but alas everywhere is still out of stock so settled on buying Maizena (cornflour).  On the back of the box are 4 recipes, one of which is for a Bacon, Cheese and Onion Tart which uses puff pastry for the base and includes fresh rosemary and hot English mustard.  The idea of this tart got my taste buds to stand at attention.  During the last week of Mom’s visit (yes I know, it was a long while ago) and while Pete was away on another business trip, Mom whipped it up for our dins – it was quite a lot of work for a savoury tart which was kind-of, more like a flat soufflé.  It was nice but not a huge hit with Mom and I – guess we were expecting more of a “traditional” tart – plus I couldn’t pick up the mustard at all.  No matter, it still made for an enjoyable supper.
