The 29-year old scored twice on debut for Scotland in the successful Kirin Cup campaign in Japan against Bulgaria back in 2006 but has made just one appearance since - in the same tournament.
Burke is back in the national team fold under Gordon Strachan for Wednesday night's friendly with Estonia in Aberdeen and he is planning to put his best foot forward.
"The Japan trip was excellent. It was a great feeling to make my debut and come off the bench to score two goals.
"It was like something you would read in a book.
"I have the shirt from my debut at home and I still have the Kirin Cup medal.
"It was a brilliant feeling to lift a trophy with Scotland, because it doesn't happen often.
"You don't normally need to wait seven years for a second call-up. I was 22 when I made my debut - it's been a long gap.
"It didn't happen for me after Japan, even though I was playing well for my clubs at times.
"But hopefully I can still adapt to international football.
"I was delighted and a bit surprised when I got the email to say I was being considered. I put it on the backburner for a few days but I was happy when I got the call to say I'd been picked."
