Just roll your own with a bottle of Ricard and some fresh squished ripe raspberries. You'd probably want to add a fair bit of sugar to bring out the flavour of the fruit.
Caveat: I've never done this with anisette based drinks so who knows what you'll end up with
If you want to do it properly you need to mix the stuff together, then leave it for a day, turn the bottle up and back down, do the same every day for about 3 weeks, then every week for about another 8 weeks.
If you can't wait that long I suppose you could just add raspberry cordial to Ricard.
