Well, I'm back home from vacation and I'm glad to report that the The Self-Sufficient 8-Day Garden Machine experiment was a success!
I made that watering set up to take care of my garden while I was away on a week-long romance vacation in Montreal. In the great Frenchie Canadian city, I discovered a food that I can't believe I've never eaten before: Sweet Tomato Jam. Holy crap, sweet tomato jam!

We stayed at a bed and breakfast called A L'Adresse Du Centre-Ville that went above and beyond expectations each morning preparing a 3-course breakfast for a full house of guests. The hostess served pancakes with strawberry rhubarb sauce, fruit and nut bread puddings, and a balsamic scramble with salsa, among other things. Her specialty was an assortment of fresh homemade jams with new flavors each morning, including carrot-orange, tomato-walnut, and citrus. But the jam that really blew me away was a sweet tomato-lemon!
As soon as I got home, I searched online and found a similar recipe from my fave dude Mark Bittman. It calls for tomatoes and chili peppers, which is perfect: those are the two veggies that are filling up my garden at the moment. But even though it has spicy and savory ingredients, the recipe also calls for sugar, cinnamon, and ginger, which should be interesting.
Here's the super-easy recipe I used, taken from the NY Times:
