This recipe and method was taught to me many years ago by a venerable old Greek lady...
So I did this with a few modifications. Finding wheatberries was difficult. I had to go to a natural foods store. The wheat they had was labelled as "hard red summer wheat". Pressure cooker method worked like a charm, giving the wheat a nice chewy texture. With the water, I threw in a stick of cinnamon, a couple of star anise, and three cloves. When finished cooking, this gave the wheat a nice subtle fragrance and taste. Laid out the drained wheat on a towel under a ceiling fan and it dried within two hours (I shuffled them a bit halfway through). I pretty much doubled the recipe, so along with a 1/2 cup of sesame seeds, I added a 1/2 cup of pine nuts, and ended up with 2 cups of walnuts (all toasted up separately). I crushed about half the walnuts into smaller pieces, so there would be a variety of texture. For the fruit, I used 1/2 cup of golden raisins, 1/2 cup of dark raisins (soaked in grape brandy overnight), 1/2 cup of dried cherries, and 1/2 cup of cranberries. Since the wheat dried well, I barely used a tablespoon of breadcrumbs when doing the mix. In fact, it was too dry. So I added a tablespoon of powdered sugar, then a drizzle of raw honey. That helped. I also added some fresh grated cinnamon and nutmeg, mixed it again, and packed it into my bowl. Then used the dry breadcrumbs as the dry barrier below the powdered sugar. Then decorated with raw almonds, cherries, and cranberries. Mixed it all up after it was blessed. Lightly sweet wheat with bursts of acidity from the dry fruit and a spicy finish. Many compliments on the koliva. My priest said it was nice that it wasn't so sweet or packed with candy. One lady gave me a hug afterwards (we were commemorating her husband, too) and thanked me that I made it, since everyone was able to have a good serving. Another lady said she'd love to eat that for breakfast every day.
Next time, I will have to make a batch with parsley or even try some with a bit of orange or lemon zest.
Oh, there were also about 20-30 people and some took leftovers home. In all, it probably cost 25 dollars or so, the dried fruit and walnuts, being the priciest ingredients. Totally worth it, even if I made it as a breakfast dish...freeze some for later. It's very filling.
