Vinegar isn't as effective unles they get at least a 50% mix of it with water. If you don't trust chlorine, consider its something that eventually evaoprates and leaves no real traces behind. Same in swimming pools where the sun makes it go away. Another option is to use sulfur and water mix, like sodium or potassium metabisulfate. These are used as soaks for sliced potatoes that are to be dried. It prevents oxidation and also kills mold and while yeast spores. The sulfur is used in many wine making processes and is also used to 'sanitize' the barrels it may be stored in. I much prefer the buttercup types (Kobachi, sp.) as its sweeter and richer tasting and lasts quite a long time too.

Lots of us tried this a few years back - and it was really good. it was those darn cookies that created a stir - where to get them - lol. Butternut Squash Lasagna Recipe courtesy Giada De Laurentiis Posted by LoriJean Recipe Summary Difficulty: Medium Prep Time: 30 minutes Inactive Prep Time: 15 minutes Cook Time: 1 hour 25 minutes Yield: 8 to 10 servings User Rating: Cook's Note: The no-boil lasagna noodles can be substituted with fresh spinach lasagna sheets. Look for fresh lasagna sheets in the refrigerated section of specialty markets. 1 tablespoon olive oil 1 (1 1/2 to 2-pound) butternut squash, peeled, seeded, and cut into 1-inch cubes Salt and freshly ground black pepper 1/2 cup water 3 amaretti cookies, crumbled 1/4 cup butter 1/4 cup all-purpose flour 3 1/2 cups whole milk Pinch nutmeg 3/4 cup (lightly packed) fresh basil leaves 12 no-boil lasagna noodles 2 1/2 cups shredded whole-milk mozzarella cheese 1/3 cup grated Parmesan Heat the oil in a heavy large skillet over medium-high heat. Add the squash and toss to coat. Sprinkle with salt and pepper. Pour the water into the skillet and then cover and simmer over medium heat until the squash is tender, stirring occasionally, about 20 minutes. Cool slightly and then transfer the squash to a food processor. Add the amaretti cookies and blend until smooth. Season the squash puree, to taste, with more salt and pepper. Melt the butter in a heavy medium-size saucepan over medium heat. Add the flour and whisk for 1 minute. Gradually whisk in the milk. Bring to a boil over medium-high heat. Reduce the heat to medium and simmer until the sauce thickens slightly, whisking often, about 5 minutes. Whisk in the nutmeg. Cool slightly. Transfer half of the sauce to a blender*. Add the basil and blend until smooth. Return the basil sauce to the sauce in the pan and stir to blend. Season the sauce with salt and pepper, to taste. Position the rack in the center of the oven and preheat to 375 degrees F. Lightly butter a 13 by 9 by 2-inch glass baking dish. Spread 3/4 cup of the sauce over the prepared baking dish. Arrange 3 lasagna noodles on the bottom of the pan. Spread 1/3 of the squash puree over the noodles. Sprinkle with 1/2 cup of mozzarella cheese. Drizzle 1/2 cup of sauce over the noodles. Repeat layering 3 more times. Tightly cover the baking dish with foil and bake the lasagna for 40 minutes. Sprinkle the remaining mozzarella and Parmesan cheeses over the lasagna. Continue baking uncovered until the sauce bubbles and the top is golden, 15 minutes longer. Let the lasagna stand for 15 minutes before serving. *When blending hot liquids: Remove liquid from the heat and allow to cool for at least 5 minutes. Transfer liquid to a blender or food processor and fill it no more than halfway. If using a blender, release one corner of the lid. This prevents the vacuum effect that creates heat explosions. Place a towel over the top of the machine, pulse a few times then process on high speed until smooth.

I agree with Annie on the interchangeable part....but I prefer hubbard to butternut. There really are lots of varieties of winter squash....all of them with subtle differences. I find acorn stringy, butternut a little dense, some delicata a little watery, hubbard HUGE and sometimes stringy, Marina del chioggia has a bit of a smokey taste....and I am still searching for the elusive galleux....said to be the sweetest and most delectable. And it must be, a friend gave me one and I left it outside for a bit as a fall decoration and the critters ate it up!! In spite of stringy, watery etc...I love all winter squashes!!

Thanks--since the fruit is already setting and growing rapidly, it shouldn't be a problem. There's a good week before the temperatures here even resembles 'chilly', and quite a few weeks after that before the first frost. I've found that if tomatoes are planted over a more manageable period of several weeks, the 'tomato tsunami' is spread over a much longer season, and yield isn't affected. Happy gardening! Rick in CT
