Hay mulch has been giving me the same excellent results of soil improvement. I have a ring around the figs with pine mulch up to the trunk. The earthworm and other soil life have improved drainage and loosened the soil. We have started mulching new planting areas and throwing kitchen scraps there for the chickens. In no time, the soil has been worked by the worms and is easy to dig, plus weeds are reduced. Worms greatly improve structure and nutrient availability of soil passed through thier bodies, so I'm really liking this, reduces work for me.
I also grow elderberries in the lower area of my yard where the soil is moist and rich. My first elderberries were from roadside collections, selecting for flavor of the raw berries. I have added commercial varieties Bob Gordon, Voltra, Wyldewood and Nova. This will be the first year for fruit, and I will try making wine and syrup. I like wild foods, and elderberries are one of the highest antioxidant fruits. They have also been proven to shorten the duration of flu.
I have not tried elderflower fritters, but I have tried this with black locust and wisteria flowers. They were a big hit with everyone, including the kids! The floral flavor really comes through. The key is a very thin batter. Fry it up and sprinkle with powdered sugar, delicious!
