Hi Judith, it's so interesting how cultures around the world come up with similar comfort foods. As for the Calamansi, any tart citrus fruit can give you the same taste contrast (though it won't have quite the same flavor), Meyer lemons are good option or if you can find them, sour oranges.

Hi Mercy, thanks for stopping by! I've never had the two together, but I can totally see how they'd go together. The only thing is, when I see tokwa’t baboy it makes me want to have a beer! 🍻 I've never had Arroz Caldo made with chicken feet, but if I had to guess I'd say it's probably pretty similar to this as I make the stock for this using chicken wings (has a similar cartilage and skin content to chicken feet, which makes it ultra rich).
