I was able to have a couple of Argentinian pandulce and they were closer to Pan Dolce from Genova (a local thing in Genoa and Liguria) than to Panettone from Milan (now widespread across all Italy). So, don't be scared to try the latter if you have the chance! It is more fluffy and less loaded with stuff. I tried Pandulce in Italy only once and I can't really remember its taste, however I read the recipe and I believe here in Argentina they use a modified version (with more exotic fruit, less candied fruit and different aromas).
I made pandoro myself. I managed to get a decent result by replacing 10% of the flour amount of the recipe with gluten (found "in polvo" in a dietetica shop). The raising times where 30% slower than the ones in the original recipe I followed (the one I used also back home), but overall I was very satisfied with the result.
Next, I am gonna try to make pizza dough again by using 10% of gluten.
