If you're not sure what furikake is, see the first bullet under "Some
final hints" below.
wet ingredients: 5.3 oz butter (1 1/3 stick) 3 T sugar 5.6 oz light corn syrup (½ C) 2 t shoyu (soy sauce) 1.8 oz vegetable oil (¼ C) dry ingredients (for example): 5 oz honeycomb cereal (1/3 box) 4 oz crispix cereal (1/3 box) 5 oz cheerios cereal (1/3 box) 1 oz furikake (½ bottle) 3 oz butter snap pretzels (1/3 bag), add last 12 oz honey roasted peanuts (1 can), add last 1. Heat wet ingredients to dissolve sugar. 2. Toss with dry ingredients to coat. 3. Bake at 250º for 1 hour, stirring every 15 minutes. 4. Cool. Store in airtight container.
The above recipe is the result of many trials tailored to meet several requirements, the primary one being the capacity of my large 17x"12x"2" rectangular roasting pan(!). I studied a half dozen recipes I found online back in 2004, then started with one that sounded the most promising (unfortunately, the page longer exists so I cannot link to it).
The next step was to choose the dry ingredients. I wanted to use Bugles crispy corn snacks, but they're really hard to find in our local supermarkets. In addition to taste, another consideration was volume relative to my aforementioned rectangular pan. It turns out one 14.5 oz box of Honeycomb cereal, one 12 oz box of Crispix cereal, and one 9 oz bag of Snyder's butter snaps pretzels will make two pans of dry ingredients.
The original recipe for the wet ingredients was not quite enough for the selected dry ingredients, plus it was too strong on shoyu and too light on butter and sweetness, so much tweaking occurred over the next several trials. I also reduced the furikake from one whole bottle down to a half bottle. The honey roasted nuts were a later addition. Still later I tried adding a third box of cereal, to add another taste and to make three pans of mix instead of two. At this point I started going with 1 1/3 sticks of butter, to evenly divide a 4-pack of sticks into three batches. We thought Cheerios came out better than Rice Chex.
To be truthful, each time I make this it's a little different, because I'll just use what I happen to have on hand.
This is obviously not a low carb snack. What I do nowadays is add extra
nuts, and eat a few of those while others eat the cereal bits.
