I love the sun. While the rest of my family celebrates the advent of cloudy, cooler fall days, I mourn the loss of summer and the absence of constant, life-giving rays on my skin. I often refer to the flaming ball of gas we revolve around as My Friend Sun.

Given my heliophile leanings, I was surprised to discover how intimidated I was by the Solavore Sport, a solar oven I recently had an opportunity to try.

The first thing that threw me was its extreme low-techness. A black, 9-pound, angular box with a lid—that’s it? No buttons? No tricky assembly instructions? In this age of high, and ever higher, tech, I felt a bit skeptical that something that looked so basic could properly cook my food.

I then fretted about the fickleness of the weather. I’m blessed to live in Denver, which sees the sun roughly 300 days a year, but even so, conditions here can change in a blink. What if I set out my dinner to cook right before clouds rolled off the Rockies and obscured the sun? Or what if I left the food in too long? Or not long enough? Or I set the box out at the wrong angle?

Finally—at the nudge of my husband, who astutely observed I was overthinking the whole thing—I washed, quartered and seasoned some golden potatoes and set them out to roast, roughly following a recipe that came with the oven. The result? After two hours, I had perfectly tender, perfectly delicious roasted potatoes that my whole family loved.

This success bolstered my courage, and I decided to try baking, which is ever-so-slightly higher tech, because it requires you to attach reflectors on top of the lid. And this time, I used a regular recipe—for corn muffins—versus one tailored for the Solavore. I had to wing it on the cooking time, because in one spot, the manual says recipes usually take double what they would in a conventional oven, while in the section on baking it says cookies usually take 1.5 hours—far more than the usual 10 minutes in the oven. And should I cover them or not? I couldn’t tell. I decided to leave them uncovered in the solar oven for one hour—which turned out to be just right. The muffins turned out moist and flavorful.

And with that, my solar-cooking fears disappeared. Not only did I end up with two excellent dishes, but I did so in a perfectly green manner, without spending a penny on fuel —and with a dash of cooking adventure sprinkled in. According to the manual, I can use the Solavore all winter, even when it’s below zero, as long as I can see my shadow. I can’t think of a better way to bond with My Friend Sun until My Beloved Summer comes back again next year.
